Drill bit AWTools AW42816 — metal and wood drilling, standard shank

AWTools AW42816 is a versatile drill bit designed for general-purpose drilling in construction, renovation and DIY tasks. Made of 40CR alloy steel with a carbide tip and two cutting edges, it provides effective penetration in hard materials. The double spiral flute improves chip evacuation and cooling during operation, while the grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers for safe, stable drilling.

Advantages

The combination of 40CR alloy steel and a carbide tip delivers durability and cutting performance when drilling into masonry and stone. Two cutting edges ensure a consistent hole and reduced walking at the start, and the double spiral flute helps remove debris and reduce heat buildup. The grooved SDS+ shank prevents accidental slippage in the chuck, making the bit suitable for repetitive tasks with hammer drills and rotary hammers.

Suitable for

• Drilling holes in masonry and concrete
• Working with granite, natural stone and brick
• Installing anchors, dowels and fasteners in construction
• Tile drilling where hammer action is required

Key specifications

• Material: 40CR alloy steel with carbide tip
• Cutting design: two cutting edges
• Flute: double spiral flute for chip evacuation
• Shank type: grooved SDS+ shank for hammer drills and rotary hammers
• Intended materials: masonry, concrete, granite, natural stone, brick, ceramic tiles

How to use

Select an appropriate drill and secure the AWTools AW42816 bit in the SDS+ chuck according to the tool manufacturer’s instructions. Use the hammer or rotary hammer function for masonry and stone as required. Begin drilling at low speed to establish the hole, then increase speed and apply steady pressure. Periodically withdraw the bit to clear debris and allow cooling; the double spiral flute will assist with material removal. Follow safety practices such as wearing eye protection and using suitable anchors for the drilled hole.

Usage recommendations

Use the AWTools AW42816 with compatible SDS+ hammer drills and rotary hammers for best results in hard materials. Avoid excessive lateral force to preserve the carbide tip, and clear debris regularly to maintain cutting efficiency. For tile and ceramic work, use controlled hammer action and verify bit condition before use.
