Drill bit AWTools AW42842, weight 133 g

AWTools AW42842 drill bit with a net weight of 133 g is designed for general drilling tasks in hard mineral materials. Made from 40Cr alloy steel and fitted with a carbide tip, the bit combines a durable body with a hard-wearing cutting point. A double spiral flute and two cutting edges improve chip evacuation and cutting efficiency, while the grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers for demanding on-site and workshop use.

Advantages

The carbide tip provides increased wear resistance and sustained cutting performance in masonry and stone. The 40Cr alloy steel body balances toughness and strength to resist bending and breakage during impact drilling. The double spiral flute design promotes efficient removal of drilled material and helps reduce heat build-up, extending tool life. The grooved SDS+ shank ensures reliable retention in chucks that accept SDS+ accessories, reducing the risk of the bit slipping or falling out during operation.

Suitable for

• Drilling holes in masonry and concrete
• Working with granite, natural stone and brick
• Cutting openings in ceramic tiles (with appropriate care)
• Use with hammer drills and rotary hammers for construction and renovation tasks

Key specifications

• Material: 40Cr alloy steel body with carbide tip
• Cutting geometry: two cutting edges
• Flute type: double spiral for improved chip evacuation
• Shank: grooved SDS+ for secure retention
• Net weight: 133 g
• Intended use: masonry, concrete, granite, natural stone, brick, ceramic tiles
• Suitable tool types: hammer drills and rotary hammers

How to use

Install the drill bit into a compatible SDS+ chuck, ensuring it locks into place before switching on the tool. Select the hammer or rotary mode when working in concrete, masonry or stone; use rotary-only mode for delicate ceramic tiles when a non-impact approach is required. Begin drilling at low speed to establish a guide point, then increase speed and apply steady pressure. Periodically withdraw the bit to clear debris and allow cooling; maintain consistent feed pressure without forcing the bit to avoid breakage or excessive wear.

Usage recommendations

For longer tool life and best results, use appropriate personal protective equipment, keep the bit clean of accumulated dust, and allow intermittent pauses when drilling deep holes to prevent overheating. Match drill speed and mode to the material: hammer mode for hard mineral materials and rotary mode for brittle tiles. Replace the bit when the carbide tip shows significant wear or chipping.
