Drill Bit AWTools AW42853 — metal and wood twist bit, standard shank

AWTools AW42853 is a twist drill bit designed for general drilling in a variety of materials including metal and wood, and also engineered for use in masonry and stone. The bit combines a 40CR alloy steel body with a YG8C tungsten carbide head to balance toughness with wear resistance. Its standard shank fits common drill chucks and rotary tools, while a grooved SDS+ section helps secure the bit and reduce the risk of accidental release during heavy-duty work.

Advantages

The two-cutter spiral design promotes efficient removal of chips and reduces heat buildup and vibrations, extending tool life and improving hole quality. The carbide head provides enhanced edge retention and wear resistance when drilling abrasive materials. A robust alloy-steel body offers impact strength needed for hammer drilling and rotary impact applications, while the standard shank and grooved SDS+ interface ensure compatibility and secure mounting in many drills.

Suitable for

• General drilling in metal and wood
• Drilling in masonry, concrete and brick
• Drilling in granite, natural stone and ceramic tiles
• Use with hammer drills and rotary impact hammer drills

Key specifications

• Construction materials: 40CR alloy steel body with YG8C tungsten carbide head
• Cutting geometry: 2-cutter spiral flute design for chip evacuation
• Shank type: standard shank with grooved SDS+ section for secure retention
• Intended materials: metal, wood, masonry, concrete, granite, natural stone, brick, ceramic tile
• Suitable tool types: standard drills, hammer drills and rotary impact hammer drills

How to use

Choose a drill and a chuck or SDS+ adapter that match the bit’s shank. For metal and wood, use steady rotational speed appropriate to the material and apply moderate pressure; use cutting fluid when drilling metal to reduce heat. For masonry, concrete, stone and ceramic tiles, use a hammer or rotary impact function where appropriate, start at low speed to position the bit, then increase speed while maintaining firm, controlled pressure. Periodically withdraw the bit to clear chips and keep the cutting zone free from debris.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves, dust mask) and clamp workpieces securely. Avoid excessive side loading and overheating; allow the bit to cool and replace if the carbide head becomes chipped or excessively worn to maintain safe and effective drilling performance.
