About this item
- 【Sturdy and Durable】- Made of premium titanium-coated High Speed Steel 4341 , perfect for use on both softwood and hardwood. The upgraded chamfer blade with a stepped design minimizes cutting resistance, provides superior cutting power and maximizes durability. Hardness: HRC60
- 【Unique Two-Flute Design】- Featuring a dual-edge cutting design, these countersink drill bits eliminate chatter and ensure smooth, precise finishes. Compared to single-blade bits, they offer faster cutting, ideal for larger or deeper countersinks.
- 【Standard 90°Angle】- Designed with sharp blades and an 90-degree countersink angle to ensuring the screw head fully countersinks into the hole. These bits deliver fast, clean pilot holes for a snug screw fit. Drill, countersink and counter bore in one step and maximize efficiency. Match the most commonly used bolts/screws you might encounter.
- 【Versatile Application】- Equipped with a 1/4" hex shank meet all your daily needs. These countersink drill bits are compatible with a wide range of tools, including hand drills, impact drills, bench drills and electric drills. Adjustable depth settings accommodate various wood thicknesses, though extended use on hardwood is not recommended.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
