## Summary description

Abraboro HSS-G countersink (model AB91030250) with working diameter range 3.8–25.0 mm and 67 mm depth. Made from high-speed steel (HSS-G), suitable for deburring, chamfering and enlarging holes in metal and other machinable materials. Designed for use with drills or milling machines in metalworking and fabrication workshops.

## Long description

Abraboro HSS-G countersink AB91030250 is a high-speed steel tool designed for creating chamfers, deburring edges and enlarging existing holes. The working diameter ranges from 3.8 to 25.0 mm and the tool features a cutting depth of 67 mm, which allows for reliable machining of through-holes and deeper recesses. Manufactured from HSS-G material, this countersink offers a balance of hardness and toughness suitable for processing a variety of machinable metals and other materials when used in drills or milling machines.
Advantages
The HSS-G construction provides good wear resistance and heat tolerance during continuous cutting operations. Its wide diameter range makes it versatile for different hole sizes without frequent tool changes. The 67 mm depth gives extended reach compared with standard countersinks, enabling work on deeper components and assemblies. The design is compatible with common metalworking equipment and supports clean chamfers and burr-free edges when used with appropriate speeds and feeds.
Suitable for
Deburring and edge chamfering of metal parts
Enlarging and finishing holes in steel, aluminum and non-ferrous alloys
Use with bench drills, drill presses and milling machines
Workshop fabrication, maintenance and prototype machining
Key specifications
Material: high-speed steel (HSS-G)
Working diameter range: 3.8–25.0 mm
Cutting depth: 67 mm
Application: countersinking, deburring, chamfering, hole enlarging
Compatibility: drills and milling machines
How to use
Secure the workpiece firmly and select appropriate clamping to prevent movement. Fit the countersink into the drill chuck or milling spindle and set the machine to a suitable rotational speed for the workpiece material. Approach the hole gradually, applying steady feed pressure and allowing the HSS-G cutting edges to remove material without excessive lateral force. Withdraw periodically to clear chips and check the chamfer or hole size; adjust speed or feed as needed to achieve a clean edge finish.
Lietošanas ieteikumi
Use cutting fluid or coolant when working with harder steels to reduce heat buildup and extend tool life. Inspect the cutting edges regularly for wear and regrind or replace the tool when edge deterioration affects finish quality. For best results on thin-walled parts, support the material to avoid distortion during countersinking.
