Drill bit KWB 266610 — SDS-Plus rotary hammer bit, 10 mm diameter, 160 mm length

KWB 266610 is an SDS‑Plus rotary hammer drill bit with a 10 mm cutting diameter and 160 mm overall length. It features a tungsten‑carbide tipped head with extra‑hard Tungsten‑Titanium‑Carbide tips and diamond‑ground cutting edges. The bit is high‑temperature brazed and formed with an MS‑5 spiral flute for efficient chip removal and is finished with ground surfaces in a copper colour. It is designed for use in rotary hammers that accept SDS‑Plus shanks and have a hammer‑stop function.

Advantages

The carbide‑tipped, diamond‑ground cutting edges and high‑temperature brazing deliver durable cutting performance and resistance to wear when drilling in abrasive or hard materials. The MS‑5 spiral design promotes rapid removal of dust and debris from the hole, improving drilling efficiency. The SDS‑Plus shank ensures secure, vibration‑resistant engagement with compatible rotary hammers.

Suitable for

• Masonry and concrete
• Natural stone such as granite and marble
• Reconstituted stone and brick
• Ceramics, glass and crystal
• Plastics and acrylics
• Hard and softwoods
• Alloyed and unalloyed steels (light drilling/spotting)

When it may not be suitable

This drill bit is optimized for rotary hammer use and aggressive materials; it may not be the best choice for precision drilling in very thin or delicate materials where minimal chipping is required. For applications that require standard twist‑drill geometry, very slow feed rates, or exclusively hand‑held, non‑hammer drilling, a specialised twist or masonry bit may be more appropriate.

Key specifications

• Cutting diameter: 10 mm
• Overall length: 160 mm
• Shank type: SDS‑Plus
• Tip material: Tungsten‑carbide with Tungsten‑Titanium‑Carbide extra hard tip
• Cutting edge: Diamond ground
• Flute type: MS‑5 spiral for chip removal
• Finish: Copper coloured, ground surfaces

How to use

Insert the SDS‑Plus shank into a compatible rotary hammer and ensure it locks in place. Select hammer‑drilling mode for masonry, concrete, stone or similar materials. Apply steady axial pressure and allow the drill and tip to cut without excessive force; withdraw periodically to clear chips if drilling deep holes. For use in non‑masonry materials, consider disabling hammering if the tool supports a hammer‑stop function and proceed at an appropriate speed for the material.

What to consider before purchase

• Confirm your rotary hammer accepts SDS‑Plus shanks.
• Match drill diameter and length to hole and fixture requirements.
• Consider material to be drilled—carbide tips suit hard, abrasive materials.
• For delicate or precision work, evaluate alternative bit geometries.

Usage recommendations

Use the KWB 266610 in hammer‑drilling mode for masonry and concrete; switch off hammering for drilling glass, ceramics or metals where impact action could cause damage. Maintain moderate feed pressure and retract occasionally to remove chips and prolong bit life.
