Drill bit Abraboro HSS cylindrical 8 mm AB41908000

Abraboro HSS cylindrical drill bit 8 mm (model AB41908000) is a high-speed steel twist drill designed for general metalworking and workshop use. With an 8 mm cutting diameter and a cylindrical shank, this drill bit is intended for clean, accurate holes in steel, nonferrous metals and many plastics. The HSS material provides wear resistance and thermal stability for routine drilling tasks in maintenance, repair and fabrication environments.

Advantages

The high-speed steel construction offers durability and reliable edge retention during repeated drilling operations. The standard cylindrical shank ensures compatibility with common drill chucks and hand drills, while the geometry of the flute and point promotes controlled chip removal and consistent hole quality. Its straight shank and 8 mm diameter make it a practical choice when precise, standard-size holes are required.

Suitable for

• Drilling through mild and medium steel
• Work on nonferrous metals such as aluminum and brass
• Drilling holes in many thermoplastics and composite plastics
• Workshop maintenance, repair and general fabrication tasks
• Use with hand drills and drill presses that accept cylindrical shanks

Key specifications

• Cutting material: high-speed steel (HSS)
• Cutting diameter: 8 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Tip style: twist drill point suitable for general-purpose drilling
• Typical applications: metalworking, nonferrous metals, plastics

How to use

Secure the drill bit firmly in a compatible chuck so the shank is held straight with minimal runout. Select an appropriate spindle speed and feed for the 8 mm HSS bit based on material — lower speeds for harder steels, higher speeds for softer metals and plastics. Use cutting fluid when drilling ferrous metals to reduce heat and prolong tool life. Start with a center punch or pilot hole if high positional accuracy is required, and apply steady pressure to avoid walking or chattering.

Usage recommendations

For best results, match drill speed and lubrication to the work material: use coolant or cutting oil for steel, moderate speed for aluminum, and reduced pressure with higher speeds for plastics to prevent melting. Inspect the cutting edges before use and replace the bit if wear or chipping is observed to maintain hole accuracy and surface finish.
