Drill bit Abraboro HSS tapered 22 mm, model AB44522000

The Abraboro HSS tapered drill bit 22 mm (model AB44522000) is a high-speed steel cutting tool designed for drilling and progressive hole enlargement in metal. Its tapered, conical geometry allows controlled removal of material and countersinking in steel and non-ferrous metals. The drill bit is suitable for use in hand-held drills and bench drills in workshops, maintenance shops and metal fabrication environments where accurate, wear-resistant drilling is required.

Advantages

The HSS material provides good wear resistance and heat tolerance during continuous drilling operations. The tapered profile enables progressive cutting, which reduces radial forces and facilitates smooth enlargement of holes without the need for multiple standard-size bits. The bit's geometry supports both drilling and countersinking functions, reducing tool changes and improving process efficiency when working with steel and softer metals.

Suitable for

• Drilling and progressive hole enlargement in steel
• Countersinking and deburring metal components
• Workshop maintenance and repair tasks
• Metal fabrication with hand-held or bench drills

Key specifications

• Material: high-speed steel (HSS) for heat resistance and durability
• Cutting shape: tapered/conical geometry for progressive hole making
• Nominal diameter: 22 mm cutting size
• Primary application: drilling and countersinking in steel and non-ferrous metals
• Compatible tools: hand-held drills and bench (drill press) machines

How to use

Secure the workpiece and select appropriate clamping or jigging to prevent movement. Fit the tapered HSS bit into the drill chuck and ensure it is centered and tightened. Start drilling at low speed to establish the pilot entry, then increase speed as appropriate for the metal being cut while applying steady axial pressure. Use cutting fluid or lubricant when drilling steel to reduce heat and prolong tool life. For countersinking, control depth by monitoring progress and stopping when the desired taper or chamfer is formed.

Usage recommendations

For best results, use appropriate cutting fluid when working with steel, maintain stable workpiece clamping, and operate at speeds and feed rates suitable for HSS tools. Inspect the cutting edge regularly and resharpen or replace the bit when wear affects hole quality.
