Which Diamond Hole Saw Kit Cuts Tile Without Cracking It
The Neiko 10926A 5-piece kit leads for its wide 1/4 inch to 1-3/8 inch size range and hex shank compatibility. The QEP 118Q3 offers a lower-cost option focused on common plumbing sizes. The Diamond Everlasting 5-piece set suits porcelain tile specifically, where slower, steadier cutting prevents glazing.
Plumbing and fixture holes in ceramic, glass, or marble tile are where the Neiko 10926A 5-piece kit fits best. Hex shanks fit a cordless drill directly, and five sizes from 1/4 inch to 1-3/8 inch cover most common jobs. Dense porcelain wears its continuous rim faster, so buyers working mostly in porcelain should look at a set built specifically for that material instead.
Sizes, shank types, and material ratings vary between brands that all claim to cut tile, which makes these kits hard to compare at a glance. We compared diamond grit type, size range, shank compatibility, and owner feedback on porcelain, glass, and ceramic performance across seven current Amazon listings.
The best picks, ranked
Neiko 10926A 5-Piece Diamond Hole Saw Kit
Five diamond grit hole saws span 1/4 inch to 1-3/8 inch in the Neiko 10926A’s case, with hex shanks that fit any cordless drill without an adapter. Owners report clean holes in ceramic, glass, and marble tile with steady water cooling. The case keeps sizes organized for repeat plumbing and fixture jobs.
Pros
- Five sizes cover most fixture holes
- Hex shank needs no separate arbor
- Case keeps bits organized
Cons
- Continuous rim wears faster on dense porcelain
- No pilot guide for off-center starts
QEP 118Q3 3-Piece Diamond Hole Saw Kit
Three sizes matching the plumbing holes tile installers drill most often make up the QEP 118Q3. Round shanks thread onto the included arbor for extra stability during long cuts. Keeping the lineup small holds the price down without dropping the sizes people reach for most, and reviewers note it handles ceramic and porcelain without a rented core drill.
Pros
- Lower cost than 5 or 6 piece kits
- Arbor adds stability during cutting
- Sized for real plumbing jobs
Cons
- No sizes for smaller anchor holes
- Arbor assembly adds a setup step
MASO 5-Piece Diamond Drill Bit Hole Saw Set
Small diameter diamond bits for anchor holes, tile edges, and glass drilling fill out the MASO 5-piece set. Hex shanks fit cordless drills directly. Build quality trails premium brands, so these bits suit occasional home projects rather than daily contractor use, and reviewers describe the set as an inexpensive way to try diamond drilling before buying a pricier kit.
Pros
- Lowest price point in this roundup
- Hex shank fits any drill directly
- Enough sizes for small anchor holes
Cons
- Diamond coating wears faster under heavy use
- Not rated for thick porcelain or stone
Diamond Everlasting 5-Piece Diamond Hole Saw Drill Bit Set
Porcelain tile glazes over if a bit overheats, and this set targets that problem directly. Its continuous rim is built for slower, steadier feed pressure rather than fast cutting. Five sizes from 1/4 inch to 1-3/8 inch cover most porcelain fixture holes, though owners report needing constant water to keep the rim from clogging on dense material.
Pros
- Designed around porcelain’s density
- Same size range as top overall pick
- Steady feed reduces glazing risk
Cons
- Slower cutting speed than general-purpose kits
- Needs constant water, not a quick dry job
EEZ-Y 6-Piece Diamond Hole Saw Drill Bit Set
Glass and thinner ceramic tile suit this kit better than dense porcelain or stone. Six sizes give finer control for mosaic or glass tile edges prone to cracking. Fine starter points help center the bit on slick glass surfaces, according to reviewer feedback, and hex shanks fit cordless drills without an adapter.
Pros
- Six sizes for fine control on glass
- Fine starter points center more easily
- Hex shank fits standard drills
Cons
- Not built for porcelain or natural stone
- Smaller size range than plumbing-focused kits
DEWALT D180009 Diamond Hole Saw, 1-3/8-Inch
A standalone 1-3/8 inch diamond hole saw, not a boxed kit, is what DEWALT sells here. Larger penetrations for pipes, conduit, or recessed fixtures in tiled walls are the target use. Buying one size separately avoids paying for smaller bits a renovation project will not use, and reviewers cite consistent cutting on porcelain and natural stone with steady water flow.
Pros
- No smaller sizes to pay for and not use
- Handles porcelain and natural stone
- Consistent brand reliability
Cons
- Only one size, not a kit
- Costs more per bit than a multi-piece set
IMT 6-Piece Diamond Hole Saw Kit
Six sizes spanning small anchor holes up to larger fixture cutouts fill one case in this kit. Renovators tackling different fixtures across a full bathroom remodel benefit most from that spread, rather than buyers needing one repeat size. Hex shanks fit cordless drills directly, and reviewers describe it as a reasonable middle ground between the cheapest sets and premium single bits.
Pros
- Widest size spread in this roundup
- Suits multi-fixture remodel jobs
- Hex shank fits standard drills
Cons
- Individual bits less specialized than porcelain or glass kits
- Case organization looser than top pick
Before you buy
What to look for in a tile hole saw kit Diamond grit replaces the teeth found on wood or metal hole saws. Continuous rim coating handles porcelain, ceramic, glass, and natural stone alike, while electroplated rims cut faster but wear sooner. Shank type matters just as much as grit choice, since hex shanks fit standard drill chucks with no adapter and round shanks need a separate arbor. Wet drilling extends bit life and keeps dust down, and a spray bottle or wet sponge works fine for occasional holes. Size range varies widely between kits, so match the case to the fixtures you actually plan to install.
Matching hole size to common fixtures Shower valves and shower arms typically need a hole between 1/2 inch and 3/4 inch. Towel bar anchors and toilet paper holders often call for 1/4 inch to 3/8 inch instead. Recessed fixtures and pendant lights can require 1-3/8 inch or larger. A three-piece kit like the QEP 118Q3 covers the most common plumbing sizes without extra bits sitting unused. Renovators installing different fixtures across multiple rooms are better served by wider five- or six-size kits.
Porcelain vs glass tile: does the bit type matter? Density separates porcelain from ceramic and glass, and that difference changes how a bit should be used. Overheating a bit on porcelain glazes the surface and stalls the cut. Diamond Everlasting markets its 5-piece set specifically for porcelain, using a continuous rim built for slower, steadier pressure. Lateral pressure cracks glass tile more than heat does, so a lighter touch and constant water matter more there than grit density. EEZ-Y’s kit targets that lighter, glass-focused use case with finer starter points.
Cutting large holes for pipes or recessed lighting Standard kits top out around 1-3/8 inch, which misses larger plumbing penetrations. Wider pipe sleeves and recessed lighting in a tiled shower need a bigger single bit rather than a boxed set. DEWALT’s D180009 covers that 1-3/8 inch range as a standalone diamond hole saw. Often, buying one large bit separately costs less than a kit including sizes a project will never use.

Frequently asked questions
What size diamond hole saw is needed for a shower valve?
Most shower valves and shower arms need a hole between 1/2 inch and 3/4 inch, a range covered by kits like the Neiko 10926A and the IMT 6-piece set.
Can diamond hole saws cut porcelain tile?
Yes, though porcelain is denser than ceramic and glazes over if a bit overheats. Sets marketed for porcelain, such as the Diamond Everlasting kit, use a continuous rim built for slower, steadier pressure.
Is wet drilling necessary for a diamond hole saw kit?
Water cools the diamond rim and clears debris, which extends bit life significantly. A wet sponge or spray bottle works for occasional holes instead of a full wet saw setup.
How do diamond hole saw kits differ from carbide hole saws?
Carbide-tipped hole saws cut faster in softer ceramic but chip on porcelain and glass. Diamond grit grinds through hard, brittle tile instead of biting into it, which reduces cracking around the edge.
Which diamond hole saw kit works best for glass tile?
The EEZ-Y 6-piece set targets glass and thin ceramic with finer starter points that center more easily on slick surfaces, since glass cracks under lateral pressure rather than heat.
Do diamond hole saws work with a regular cordless drill?
Hex shank kits like the Neiko 10926A and the MASO set fit a standard cordless drill chuck directly. Round shank kits, such as the QEP 118Q3, need the included arbor first.
Is a diamond hole saw kit better than buying one large bit?
A kit makes sense when a project needs several different hole sizes. A single bit like the DEWALT D180009 costs less overall if you only need one larger diameter repeatedly.
How long do diamond hole saw bits last before replacing them?
Life depends on tile hardness and water use more than a fixed hole count. Owners report electroplated rims on budget sets like MASO wearing faster than continuous-rim bits under repeat porcelain use.
What is the difference between hex shank and round shank hole saws?
Hex shanks fit a standard cordless drill chuck directly, with no extra part needed. Round shanks thread onto an included arbor first, like the QEP 118Q3 kit, which adds a setup step but often improves stability during long cuts.
Our pick
Neiko’s 10926A earns the top spot because five sizes and a hex shank cover most plumbing and fixture holes without extra setup steps. Anyone drilling mostly dense porcelain should choose the Diamond Everlasting set instead, since its rim handles slower, steadier cuts. A single large hole for a pipe sleeve or recessed light is better served by the DEWALT D180009 than a multi-piece kit.
