Drill bit AWTools AW42849 — metal and wood twist bit, standard shank

AWTools AW42849 is a multi-material twist drill bit designed for drilling in metal and wood, offering a standard straight shank that fits most hand drills and drill presses. Constructed from 40Cr alloy steel with a YG8C tungsten carbide tip, this bit combines a durable body with a hard cutting head to maintain edge life during routine workshop and DIY tasks. The 2-cutter spiral geometry promotes efficient chip evacuation, reduces vibration and heat buildup, and supports consistent hole quality for fastening, repair and construction applications.

Advantages

The combination of a 40Cr alloy steel body and a YG8C tungsten carbide tip provides wear resistance and sustained cutting performance. The two-cutter spiral profile improves spoil removal and reduces friction, helping to prevent overheating and extend bit life. A straight, standard shank ensures compatibility with a wide range of drill chucks and tools commonly used in home and professional settings.

Suitable for

• Drilling in metal components for installation of fasteners and fittings
• Creating clean holes in wood for woodworking and carpentry tasks
• General workshop drilling and maintenance work
• Use with hand drills and drill presses for routine DIY projects

Key specifications

• Material: 40Cr alloy steel body with YG8C tungsten carbide tip
• Cutting geometry: 2-cutter spiral design for effective chip removal
• Shank type: standard straight shank for common drill chucks
• Intended materials: metal and wood

How to use

Secure the drill bit in the chuck of a compatible hand drill or drill press, ensuring firm clamping on the straight shank. Select an appropriate rotational speed and feed pressure for the work material—lower speeds for harder metals and higher speeds for softer woods. Maintain steady, controlled pressure and withdraw the bit periodically to clear chips when drilling deeper holes. Use cutting fluid or lubricant when drilling hard metals to reduce heat and improve tool life.

Usage recommendations

For best results, match drill speed and feed to the specific metal or wood species being drilled, avoid excessive pressure that can cause overheating, and replace the bit when signs of wear or chipping on the carbide tip appear. Store the bit in a dry place and use appropriate personal protective equipment when operating power tools.
