Drill Bit Smart SDS+ 20 mm model 17-20600

The Smart SDS+ 20 mm drill bit (model 17-20600) is a specialist masonry bit designed for rotary and hammer drills with SDS+ chucks. It offers a 20 mm cutting diameter for straightforward, repeatable holes in concrete, brick and natural stone. The fluted shaft and carbide tip are configured to evacuate dust and chips while maintaining consistent bore size during drilling operations typical in construction and renovation work.

Advantages

This SDS+ drill bit provides a durable carbide tip engineered to resist wear when drilling into abrasive masonry materials. The SDS+ shank ensures secure, impact-resistant connection with compatible hammer drills, reducing slippage and improving energy transfer. The 20 mm diameter delivers a precise bore size suitable for anchors, sleeves and conduit passage, and the flute geometry supports efficient removal of debris to maintain cutting performance.

Suitable for

• Drilling 20 mm holes in concrete for anchors and sleeves
• Creating holes in brick and block for through-fixings and conduits
• Renovation tasks requiring consistent bore diameter in masonry
• Use in rotary-hammer drills with SDS+ chucks for impact drilling

When it may not be suitable

This drill bit is not intended for use in standard drill chucks that do not accept SDS+ shanks, and it will not fit non-SDS+ tools without an appropriate adapter. It is also not designed for drilling in metal, wood, ceramic tile or glass; using it on those materials will reduce cutting efficiency and can damage the tip.

Key specifications

• Cutting diameter: 20 mm
• Intended materials: concrete, masonry, natural stone
• Shank type: SDS+ compatible
• Tip material: carbide cutting tip
• Flute design: spiral for dust and chip evacuation

How to use

Install the bit into an SDS+ compatible rotary-hammer drill until it locks into place. Use the rotary-hammer function for impact drilling in concrete and masonry, applying steady pressure without forcing the bit. Periodically withdraw the bit during long holes to clear dust and allow the flute to evacuate debris; this helps maintain cutting efficiency and prolongs tip life. For precise depth control, use a depth stop on the drill or mark the bit before starting.

What to consider before purchase

• Confirm your drill accepts SDS+ shanks
• Verify 20 mm is the required hole diameter for anchors or sleeves
• Ensure the bit is specified for masonry and concrete materials

Usage recommendations

For best results when drilling into concrete, start with a pilot location at low speed to position the bit, then switch to impact mode and moderate speed. Keep the bit cool by clearing debris regularly; when working in reinforced concrete, proceed slowly and avoid overheating the carbide tip. Replace the bit when cutting performance degrades to maintain hole accuracy.
