Drill bit Abraboro HSS-R 10.2 mm, length 133 mm, point angle 87° (pack of 5)

Abraboro HSS-R 10.2 mm drill bit, overall length 133 mm and 87° point angle, is a precision tool for general metal drilling. Manufactured from high-speed steel, this drill bit is designed to cut through steel and a range of other metals. Supplied as a pack of five identical bits, it is suitable for use in handheld drills and drill presses for through-holes and standard metalworking tasks.

Advantages

The high-speed steel (HSS-R) construction provides wear resistance and maintains cutting performance at elevated drilling speeds. The 87° point angle offers a balance between fast penetration and centered drilling, reducing the tendency to wander when starting a hole. A 133 mm overall length gives sufficient reach for many through-hole applications while maintaining rigidity for stable drilling. Packaging in a set of five ensures quick replacement of worn bits and convenient availability on the workbench.

Suitable for

• Drilling through mild and alloy steels
• General metal fabrication and maintenance tasks
• Use in handheld electric drills and drill presses
• Production of through-holes in thin to moderately thick metal sheets

Key specifications

• Material: high-speed steel (HSS-R)
• Diameter: 10.2 mm
• Overall length: 133 mm
• Point angle: 87°
• Pack quantity: 5 pieces

How to use

Secure the workpiece firmly and select an appropriate clamp or vice to prevent movement. Install the drill bit in the drill chuck, ensuring it is centered and tightened. Use cutting fluid or coolant when drilling steel to reduce heat and prolong bit life. Start at low speed to create a pilot indentation, then increase speed as appropriate for the material thickness and machine capability. Apply steady, even pressure; withdraw the bit occasionally to clear chips when drilling deeper holes.

Usage recommendations

For best results on steel, use a suitable cutting lubricant, keep moderate spindle speeds to avoid overheating, and replace bits from the pack when wear reduces cutting efficiency. Inspect bits before use for straightness and sharpness, and store them dry to prevent corrosion.
