Concrete drill bit Dedra SDS+ 16 mm WP1660

Dedra SDS+ 16 mm WP1660 concrete drill bit is designed for reliable drilling into concrete, masonry and natural stone. The bit is compatible with SDS+ rotary hammers and hammer drills, providing stable engagement and efficient impact transfer. Its length and flute profile are engineered to evacuate dust and chips during drilling, supporting continuous work in construction and installation tasks.

Advantages

The SDS+ shank ensures secure mounting in compatible tools and reduces slippage during heavy-duty hammer drilling. A reinforced head geometry improves centring and penetration in hard substrates while the optimized flute design promotes consistent debris removal. The 16 mm diameter balances hole size with structural integrity for common anchoring and conduit installation jobs.

Suitable for

• Drilling holes for anchors and wall plugs in concrete and masonry
• Creating routes for electrical conduit and plumbing sleeves
• Preparing fixing points for structural and non-structural installations
• General masonry work where rotary hammer action is required

Key specifications

• Shank type: SDS+ compatible
• Diameter: 16 mm
• Intended materials: concrete, masonry, stone
• Flute design: spiral/optimized for dust and chip removal
• Application: rotary hammer and hammer drill use with hammering action

How to use

Select an SDS+ compatible rotary hammer or hammer drill and insert the bit until it locks in the chuck. Mark the drilling location and start at low speed to establish the pilot position, then apply steady pressure and engage hammer mode for concrete and masonry. Withdraw the bit periodically to clear accumulated dust when drilling deep holes. Use appropriate personal protective equipment such as eye and ear protection and a dust mask while operating the tool.

Usage recommendations

For best results, match drill diameter to anchor or fixture requirements, use correct drill speed and hammer settings for the substrate, and replace the bit when cutting efficiency noticeably decreases to maintain clean holes and reduce stress on the tool.
