Frequently Asked Questions

Q: Are these SDS Plus drill bits compatible with standard electric hammer drills?

A: Yes. These 3mm SDS Plus drill bits feature a standard round SDS Plus shank, making them compatible with most SDS Plus electric hammer drills available on the market. The shank design ensures a secure, stable fit and efficient power transfer during use.

Q: What materials can these 3mm concrete drill bits be used on?

A: These bits are designed for hard masonry materials including concrete, red brick, marble, granite, and road surfaces. They are not intended for use on wood, metal, or soft materials — for best results, always use them with an SDS Plus hammer drill in hammer mode.

Q: How does the cross-tip design benefit drilling performance?

A: The cross-tip double auger cutter head is engineered to increase drilling efficiency by breaking up material more effectively while simultaneously channelling debris out of the hole. This reduces heat buildup, extends bit life, and delivers cleaner, faster results in masonry applications.

Q: Which pack size should I choose?

A: The 2-piece set is great for light, occasional use. The 4-piece set suits regular DIY projects where you may need a spare. The 10-piece set offers the best value for contractors, tradespeople, or anyone tackling larger-scale masonry work where bits experience heavier wear.
