Drill bit AWTools AW42805 — metal/wood drilling accessory, 54 g

AWTools AW42805 — metal/wood drilling accessory, 54 g is a compact drill bit engineered for handheld and power-tool drilling. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, this bit combines toughness with precision. Its double spiral flute promotes efficient removal of chips and dust, reducing heat buildup during continuous use. The grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers to prevent accidental release during operation. The design supports drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles when used with appropriate equipment and settings.

Advantages

The 40CR alloy steel body with a carbide tip delivers wear resistance and maintains cutting performance over repeated use. Two cutting edges provide cleaner holes and reduced wandering when starting a hole. Double spiral flutes accelerate chip evacuation to help maintain drill bit temperature and efficiency. The grooved SDS+ shank ensures secure retention in hammer drills and rotary hammers, improving operator control and safety. The bit’s lightweight and compact form factor makes it suitable for confined spaces and handheld tasks.

Suitable for

• Drilling holes in masonry, concrete and brick for anchor and fastening installations
• Punching through granite, natural stone or ceramic tiles with appropriate technique
• General repair, construction and DIY tasks requiring a compact, robust drill bit
• Use with hammer drills and rotary hammers that accept SDS+ shanks

How to use

Select a hammer drill or rotary hammer compatible with SDS+ shanks and secure the AWTools AW42805 bit in the tool’s chuck according to the drill manufacturer’s instructions. Mark the drilling point and, where applicable, start at low speed to position the bit accurately. Apply steady axial pressure and use the hammer function when drilling into concrete, masonry or stone. Maintain moderate feed pressure and avoid excessive force to prevent breaking the carbide tip. Periodically withdraw the bit to clear accumulated debris and allow cooling during prolonged drilling.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. Use water or recommended cooling methods on ceramic tiles and stone where required to reduce dust and protect the carbide tip. Match drill speed and hammer settings to the material: lower speeds for harder materials, medium to high speeds for softer masonry. Inspect the bit before use and replace if the tip is chipped or excessively worn.
