Concrete drill bit AWTools SDS+ 16 mm model AW42857

AWTools SDS+ 16 mm concrete drill bit (model AW42857) is a rotary drilling accessory designed for use with hammer drills that accept SDS+ chucks. The 16 mm diameter carbide-tipped bit is specified for drilling into concrete, masonry and similar dense substrates. Its design combines a reinforced shank with a precision-ground flute to remove dust efficiently and maintain drilling progress in construction and renovation tasks such as installing anchors, fastening fixtures and creating passage holes.

Advantages

The AWTools SDS+ 16 mm bit provides consistent drilling performance in concrete and masonry thanks to a hardened head and optimized flute geometry that evacuates debris. Its SDS+ shank ensures secure fitting and quick changeover in compatible hammer drills. The carbide tip is manufactured for resistance to wear under repeated impact drilling, supporting reliable hole accuracy and longer service life compared with standard twist bits when used in appropriate applications.

Suitable for

• Drilling anchor and plug holes in concrete and solid masonry
• Preparing mounting points for fixtures, brackets and rails
• Creating service and passage holes for pipes and conduits in renovation work
• General construction site drilling with SDS+ rotary hammer tools

Key specifications

• Drill diameter: 16 mm
• Shank type: SDS+ compatible
• Tip material: carbide-tipped cutting head
• Intended materials: concrete, masonry and similar hard substrates
• Application: rotary hammer drilling with impact action

How to use

Insert the SDS+ shank fully into the drill chuck until it locks, ensuring the tool is switched off and unplugged or the battery removed before changing accessories. Select the hammer drilling mode on the rotary hammer, position the bit perpendicular to the work surface and start drilling at low speed to establish the center. Apply steady forward pressure without forcing the bit; allow the hammer action to do the cutting. Withdraw the bit periodically to clear dust from the hole and maintain drilling efficiency. After use, remove the bit and store it dry to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Match drill length and diameter to the anchor or fastener being installed and use a depth stop or marker to control hole depth. For reinforced concrete, use controlled speed and correct feed to reduce bit wear; replace the bit when the cutting performance diminishes to maintain hole accuracy.
