Best Rotary Hammer Bits (2026): 4 SDS-Plus Sets Compared

A concrete anchor that will not hold starts with the wrong bit: the hole wanders, the bit skates across the surface, and the anchor never bites. The best rotary hammer bits cut a clean, round hole in concrete, stone and brick, clear dust as they go, and leave an anchor hole that holds. This roundup compares SDS-Plus bit and chisel sets by bit range, chisel mix, storage case and listed weight.

Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 6 November 2026). Where a listing contradicts itself, both figures are shown.

How the points were given

Each set is scored out of 10 on performance, build, value, safety and warranty, with the weights published on the How We Pick page. None states a UL, ETL or CSA listing, so all score zero on safety, and none gives a clear warranty term.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total. Where a tool neither runs on power nor lists a safety feature, safety shows n/a and the other 90 points decide.

What the listings tell you

4 listings were compared. All 4 are 17-piece SDS-Plus sets with carbide tips. 3 state bit diameters, 3 state case dimensions, and 2 state a weight. 2 list a U-shaped flute, and none states a warranty term or a safety listing. The 2 listings that state a weight disagree sharply: 1.0 lb for the WORKPRO set against 6.34 lb for the COMOWARE set, both for 17-piece sets with a case.

Buying guide: best rotary hammer bits

Bit sizes and range

Match the bit to the anchor: the sets here cover 3/16 in to 5/8 in, with the Cididu set listing the same spread as 5 mm to 14 mm. A set that states its diameters lets you pick the right bit before the first hole. The WORKPRO listing gives no diameters, so its sizes stay a guess until the case arrives.

Chisels in the set

Point chisels start a break, flat chisels pare and shape, and a U-groove chisel cuts channels. The WORKPRO and Cididu sets carry 2 point chisels and 3 flat chisels, while the WildBossy and COMOWARE sets carry 1 point chisel, 2 flat chisels and 1 U-groove chisel. Chisels turn a drilling set into a light demolition set for tile removal, shaping concrete and chasing grooves.

Shank and fit

All 4 sets use an SDS-Plus shank, and the listings state fit with most SDS-Plus rotary hammers. The WORKPRO listing names BOSCH, MAKITA and Milwaukee as compatible brands. Bits and chisels change without an adapter, so a swap mid-job stays quick. If the hammer itself still needs choosing, the best rotary hammer cordless roundup compares cordless models.

Carbide tips

All 4 sets list carbide tips, and 3 name the grade as YG8C cemented carbide, listed for hardness and durability in concrete, stone and brick. The Cididu set lists carbide without a grade and notes the tips keep an edge under high impact work.

Case and storage

3 listings size the storage case at 11-39/64 in by 9 in by 2-13/64 in, and the Cididu set comes in a storage box with compartments. A case keeps bits sorted by size and keeps chisels from knocking against each other. Check the case size against the shelf or drawer where the set will live.

Garage Fit Check

• Check the SDS-Plus shank against the rotary hammer before the first job; all 4 sets list SDS-Plus fit.
• Allow bench or shelf space for a case sized 11-39/64 in by 9 in by 2-13/64 in, the size 3 listings state.
• Check the listed weight before carrying the case to a job: the WORKPRO set lists 1.0 lb and the COMOWARE set lists 6.34 lb.
• Match bit diameters to the anchors on hand: the sets cover 3/16 in to 5/8 in, and the Cididu set lists the same range as 5 mm to 14 mm.

FAQ: garage tools

What size rotary hammer bits do I need for concrete anchors?

The sets here cover 3/16 in to 5/8 in, and the Cididu set lists the same spread as 5 mm to 14 mm. Check the anchor maker’s stated hole size, then pick the matching bit from the set.

Do these bits fit any rotary hammer?

All 4 sets use an SDS-Plus shank, and the listings state fit with most SDS-Plus rotary hammers. The WORKPRO listing names BOSCH, MAKITA and Milwaukee. A hammer with a different shank needs a different bit set.

What are the chisels for?

Point chisels start breaks, flat chisels pare, shape and remove tile, and the U-groove chisel cuts channels and grooves. The sets pair chisels with drill bits so one case covers drilling, chipping and grooving.

What does YG8C carbide mean?

YG8C is the cemented carbide grade the makers list for the bit tips, chosen for hardness and durability in concrete, stone and brick. The listings describe the tips as keeping an edge under high impact work.

How should I store rotary hammer bits?

Keep bits and chisels in the storage case that comes with the set; 3 listings size the case at 11-39/64 in by 9 in by 2-13/64 in. Wipe off the protective oil the Cididu listing notes on its bits and box before the first use.
