Drill bit Abraboro HSS-GS 11.5 mm x 142 mm x 94 mm pack of 5

Abraboro HSS-GS drill bits, diameter 11.5 mm, overall length 142 mm and flute length 94 mm, supplied as a pack of 5. These straight-shank twist drills are made from high-speed steel (HSS-GS) for metalworking applications and are suitable for use in handheld drills and drilling machines. The geometry and material are intended to provide dependable cutting performance when making precise holes in steel, iron and other similar metals.

Advantages

The high-speed steel construction offers wear resistance and heat tolerance under typical drilling loads. A straight shank enables secure clamping in chucks and drill holders, while the twist-flute design facilitates chip evacuation from the hole. Supplied in a pack of five, the set supports repeat jobs and reduces downtime from tool changes.

Suitable for

• Drilling through mild and medium carbon steel
• General metal fabrication and maintenance tasks
• Workshop and on-site drilling with handheld or bench machines
• Preparation of holes for fasteners and fittings in metal components

How to use

Select the appropriate drill speed and feed for the metal type and thickness, secure the bit in the drill chuck ensuring correct centering, and use cutting fluid where applicable to reduce heat and improve tool life. Start drilling at low speed to establish the center, then apply steady pressure and maintain alignment until the hole is complete. Withdraw periodically if chips are clogging the flutes, and replace the bit when wear affects hole quality.

Usage recommendations

Use cutting or cooling fluid for improved performance on harder metals, clamp the workpiece securely, and choose drill speeds consistent with HSS tooling recommendations to prolong bit life and ensure accurate holes.
