## Summary description

Abraboro countersink made of HSS-Co designed for drilling/reaming holes with a diameter range of 2.0–8.3 mm. The tool has a cutting length of 50 mm and is suitable for creating chamfers, deburring and preparing holes for screws and fittings in metalworking and mechanical assembly. High-speed steel with cobalt alloy provides wear resistance for machining steels and alloys.

## Long description

Abraboro HSS-Co countersink for 2.0–8.3 mm holes is a precision cutting tool designed for preparing, chamfering and deburring holes in metalworking and mechanical assembly. Manufactured from high-speed steel with cobalt alloy, this countersink combines hardness and heat resistance to maintain cutting performance when working with steels and common metal alloys. Its 50 mm cutting length enables deeper engagement for through-holes and partial-depth operations while keeping tool stability and accuracy.
Advantages
The HSS-Co construction increases wear resistance and thermal stability compared with standard HSS, extending tool life when machining tougher materials. The specified diameter range covers a wide span of drill and reaming sizes, reducing the need to change tools for matching screw and fitting preparations. A 50 mm cutting length gives reliable reach into deeper holes and helps to produce consistent chamfers and clean deburring results. The geometry is optimized for metal cutting to reduce chatter and improve surface finish.
Suitable for
 Creating chamfers and countersinks for screw heads and fittings in metal components
 Deburring and finishing drilled holes in steel, alloy and general metalwork
 Preparing holes for subsequent tapping or reaming operations
 Through-hole and partial-depth chamfering where extended cutting length is required
Key specifications
 Diameter range: 2.0–8.3 mm
 Cutting length: 50 mm
 Material: high-speed steel with cobalt alloy (HSS-Co)
 Intended use: countersinking, chamfering and deburring in metals
How to use
Select a suitable spindle speed and feed rate for the workpiece material and secure the workpiece to prevent movement. Mount the Abraboro countersink in the appropriate collet or chuck, ensuring concentricity and secure clamping. Start cutting at low speed to establish the chamfer, then increase speed and apply steady feed to complete the operation. Retract the tool periodically for chip clearance and cooling if machining harder alloys. Inspect the chamfer and deburred edge and adjust depth or feed as required for the desired finish.
Usage recommendations
Use cutting fluid or coolant when machining steels and alloyed materials to reduce heat buildup and extend tool life. Match spindle speeds and feed to material hardness; lower speeds and lighter feeds are recommended for harder alloys. Regularly inspect the cutting edges and replace the tool when wear affects finish quality or dimensional accuracy.
