## Summary description

Abraboro cone countersink drill bit made from HSS-Co (cobalt) for drilling and countersinking holes with cutting diameters from 3.5 to 20.5 mm and an overall length of 63 mm. Suitable for use in metalworking and general workshop tasks where combined drilling and chamfering or enlarging of holes is required. Fits standard drill chucks and is intended for professional and hobby use.

## Long description

Abraboro cone countersink drill bit in HSS-Co (cobalt) is designed for combined drilling and countersinking or enlarging of holes with cutting diameters from 3.5 to 20.5 mm and an overall length of 63 mm. The single-piece conical geometry enables progressive cutting across a wide diameter range, so a single tool covers multiple hole sizes. Manufactured from high-speed steel with cobalt content, the bit offers improved wear resistance and heat tolerance compared with standard HSS, making it suitable for repeated use in metalworking and general workshop applications.
Advantages
The HSS-Co material provides higher hardness and thermal stability for longer tool life under elevated cutting temperatures. The cone-shaped flutes allow smooth chip evacuation and gradual engagement with the workpiece, reducing the risk of jamming or excessive burrs. Its dimensions — cutting Ø 3.5–20.5 mm and 63 mm overall length — give a compact, versatile option that fits standard drill chucks for both professional and hobby tasks.
Suitable for
Drilling and countersinking holes in steel and non-ferrous metals
Enlarging existing holes to stepped diameters within the 3.5–20.5 mm range
Workshop maintenance, fabrication, and repair work
Use with portable drills and drill presses that accept standard chucks
Key specifications
Material: high-speed steel with cobalt (HSS-Co)
Cutting diameter range: 3.5–20.5 mm
Overall length: 63 mm
Tool geometry: conical/countersink with progressive cutting profile
Shank: cylindrical to fit standard drill chucks
How to use
Secure the cone countersink bit in a standard drill chuck and set the drill to an appropriate speed for the workpiece material. Start with light feed pressure to establish the initial cutting contact and then increase feed steadily until the desired diameter or chamfer is reached. For best results on harder metals, use cutting fluid to reduce friction and heat. Withdraw the tool periodically to clear chips and inspect the hole diameter and edge quality.
Usage recommendations
Use moderate speed and consistent feed when working with steel; increase speed slightly for softer non-ferrous metals. Apply cutting lubricant on steel to extend tool life and improve surface finish. Inspect the bit for wear or dulling before precision work and replace if cutting performance degrades.
