Drill Bit AWTools AW42785 — replacement/standard bit for general drilling tasks

The AWTools AW42785 drill bit is a replacement/standard bit for general drilling tasks designed for use with compatible handheld drills and rotary hammer tools. Made of alloy steel with a carbide tip and two cutting edges, this single bit is intended for routine drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles. The double spiral flute design promotes debris evacuation and helps reduce overheating during continuous use. The bit has a 130° point angle and is suitable for light workshop work, maintenance jobs and on-site repairs where a reliable spare is required.

Advantages

The combination of alloy steel body and a carbide tip provides improved wear resistance compared with plain steel bits and helps maintain cutting performance when drilling hard materials. Two cutting edges ensure stable drilling and accurate hole formation, while the double spiral flute efficiently clears dust and chips to prolong tool life. The 130° point angle balances penetration and control for a range of masonry and stone materials. Compatibility with hammer drills and rotary hammers makes the bit versatile across common construction and renovation tasks.

Suitable for

• Drilling holes in concrete and masonry for anchors and fasteners
• Working with granite, natural stone and brick
• Installing fixings in ceramic tiles with appropriate care
• Routine maintenance, light renovation and workshop drilling tasks
• Use with hammer drills and rotary hammers for impact-assisted drilling

How to use

Select a drill speed and impact setting appropriate to the material and your tool. Secure the workpiece where possible and mark the drilling point. Fit the AWTools AW42785 bit into the drill chuck or tool adapter ensuring a firm, centered grip. Start drilling at low speed to establish the hole, then increase speed and use the hammer function when penetrating hard masonry or stone. Apply steady pressure without forcing the bit to prevent breakage or excessive wear. Withdraw the bit occasionally to clear debris and allow cooling if drilling deep holes.

Usage recommendations

Use personal protective equipment including safety glasses and hearing protection. For ceramic tiles, start with a pilot hole at low speed and consider using a tile-specific method to avoid chipping. Avoid excessive lateral loads on the bit and allow periodic pauses for cooling during prolonged drilling in dense materials.
