Drill bit AWTools AW42813 — general-purpose metal and wood drill bit, model AW42813

AWTools AW42813 — a general-purpose drill bit designed for routine drilling in both metal and wood as well as many hard materials. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, this rotary accessory is intended for use with handheld and bench drills, including hammer drills and rotary hammers when working in masonry-type materials. The double spiral flute design promotes efficient chip evacuation and helps reduce heat buildup during continuous drilling operations. The grooved SDS+ shank secures the bit in compatible chucks to prevent accidental disengagement.

Advantages

The 40CR alloy steel body combined with a carbide tip delivers abrasion resistance and extended tool life compared to plain-steel bits. Two cutting edges provide stable, centered entry and consistent hole quality across a range of materials. The double spiral flute clears chips effectively, lowering the risk of clogging and overheating during prolonged use. An SDS+ grooved shank ensures a firm mechanical connection with compatible hammer drill systems, improving transmission of impact force and reducing slippage.

Suitable for

• Drilling holes in masonry, concrete and brick
• Boring into natural stone, granite and ceramic tiles
• Routine metal and wood drilling with handheld or bench drills
• Repair, maintenance and general DIY projects requiring standard drilling performance

Key specifications

• Material: 40CR alloy steel body with carbide tip
• Cutting geometry: two cutting edges
• Flute design: double spiral flute for chip evacuation
• Shank type: grooved SDS+ shank for secure fitting
• Compatible tools: hammer drills and rotary hammers, handheld and bench drills

How to use

Select a drill and chuck compatible with the SDS+ shank and secure the AWTools AW42813 bit firmly. For masonry, concrete or tile, use the hammer or rotary hammer mode of the tool and allow the bit to work at a steady pressure without forcing it; withdraw periodically to clear debris if necessary. For metal and wood, use standard rotary drilling mode, appropriate speeds and cutting lubricant for metal where applicable. Always follow the drill manufacturer's instructions and wear appropriate eye, hand and respiratory protection when drilling.

Usage recommendations

Use lower speeds and steady pressure when penetrating hard stone or tile to avoid chipping; for metal, use cutting fluid and moderate speed to extend tip life. Replace the bit when signs of excessive wear or loss of cutting performance appear to maintain drilling quality and safety.
