【High-Quality Material】These drill bits are made of HSS4241, which is rust-resistant and durable. The cutting edge is smooth, with no chatter or fluted edges. Ideal for clean and precise milling, chamfering, or countersinking of round holes in workpieces.

【Internal Chip Removal】The countersunk head drill bit removes chips during cutting, reducing clogging and preventing metal spatter, resulting in faster, cleaner, and quieter cutting. The round handle is compatible with a variety of drill systems.

【Superior Efficiency】The HSS-coated chamfering tool offers high precision and sharpness. The tip is angled at 90° for clean and accurate milling. Increase productivity and save time and energy in home and industrial operations.

【WIDE APPLICATION】 Suitable for cutting plywood, wood, acrylic, PVC panels, plastic, and metal. When working with materials, the drill bit should be kept cool between drilling holes. (Note: It is necessary to use a bench drill; a hand-held electric drill cannot be used.)
