Drill bit Abraboro HSS-GS 8.0 mm x 117/75, metal drilling, pack of 10

Abraboro HSS-GS drill bit 8.0 mm x 117/75 in a pack of 10 is a set of general-purpose metalworking bits designed for use with handheld and machine drills. Each bit has a nominal diameter of 8.0 mm, an overall length of 117 mm and a working (cutting) length of 75 mm. Manufactured from high-speed steel (HSS-GS), these drill bits are intended for drilling steel and other metals where wear resistance and heat tolerance are required for routine maintenance, assembly and fabrication tasks.

Advantages

The HSS-GS material provides a balance of hardness and toughness suitable for general metal drilling. The 75 mm working length gives stable guidance through typical sheet and plate thicknesses while the 117 mm overall length allows access to recessed or partially obstructed holes. Supplied as a set of 10 identical bits, the pack reduces downtime for repeated operations and simplifies tool provisioning for workshops and maintenance teams.

Suitable for

• Drilling holes in structural and mild steels
• Routine maintenance and repair work with handheld drills
• Machine drilling on drill presses and pillar drills
• Assembly and fabrication tasks requiring multiple identical holes
• Workshop stock for general metalworking

Key specifications

• Diameter: 8.0 mm
• Overall length: 117 mm
• Working (cutting) length: 75 mm
• Material: High-speed steel (HSS-GS)
• Pack quantity: 10 pieces

How to use

Select an appropriate drill speed and a suitable cutting fluid or coolant for the metal being drilled. Secure the workpiece and use a center punch or pilot mark if required to prevent bit wandering. Install the 8.0 mm bit firmly in the drill chuck, align the drill perpendicular to the work surface, and apply steady, even pressure. Retract occasionally when drilling deeper holes to clear chips and reduce heat buildup. After use, clean chips from the flutes and store the bits in a dry location.

Usage recommendations

The bits are intended for general metal drilling; for hardened or stainless steels consider reduced feed rates, increased coolant, or a specialized grade. Replace bits that show significant wear, chipping or loss of cutting performance to maintain hole quality and operator safety.
