Drill Bit AWTools AW42852 — metal and wood drilling bit, model AW42852

AWTools AW42852 is a versatile drilling bit designed for general-purpose use with hand drills, hammer drills and rotary impact hammer drills. Constructed with a 40CR alloy steel body and a YG8C tungsten carbide head, this bit is intended for drilling in a range of hard and soft materials. Its 2-cutter spiral geometry promotes efficient chip removal and reduces heat and vibration during operation, while the grooved SDS+ shank secures the bit in compatible chucks to prevent accidental release.

Advantages

The combination of a 40CR alloy steel shaft and a YG8C tungsten carbide tip provides increased wear resistance and cutting performance on hard materials. The 2-cutter spiral design enhances spoil evacuation to maintain cutting efficiency and reduce overheating. The grooved SDS+ shank improves retention in compatible drill holders for safer, more stable operation. Overall, the design balances durability and usability for both metal and wood drilling tasks as well as impact drilling in masonry-type materials.

Suitable for

• Drilling metal components and sheet metal
• Drilling wooden workpieces in carpentry and furniture assembly
• Impact drilling in masonry, concrete and brick when used with hammer drill or rotary hammer
• General workshop and DIY repair tasks requiring a reliable single drill bit

Key specifications

• Body material: 40CR alloy steel
• Tip material: YG8C tungsten carbide
• Cutting geometry: 2-cutter spiral design for efficient chip removal
• Shank type: grooved SDS+ for secure retention in compatible chucks
• Intended materials: metal, wood, masonry, concrete, granite, natural stone, brick, ceramic tiles
• Suitable tool types: hand drills, hammer drills, rotary impact hammer drills

How to use

Fit the AWTools AW42852 bit into a compatible SDS+ chuck or holder and ensure it is fully engaged and locked before starting the tool. Select the correct rotational speed and, when applicable, switch to the hammer/impact mode for masonry and concrete. Apply steady, moderate pressure and allow the bit to cut without forcing; excessive force increases wear and risk of breakage. For metal and wood, use appropriate cutting speeds and consider lubricating metal workpieces to reduce heat. Clear chips periodically to maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment including eye protection and gloves. For drilling in masonry or concrete, begin with a pilot point or smaller diameter if precision is required, and withdraw the bit periodically to remove debris and prevent overheating. Match drilling speed and feed pressure to the material: lower speeds and steady pressure for masonry and higher speeds for softer wood. Inspect the bit regularly for wear or damage and replace the bit when the cutting edge is blunt or the tip is chipped.
