Drill Bit Abraboro HSS conical for metal 14.5 mm AB44514500

The Abraboro HSS conical drill bit for metal with a 14.5 mm cutting diameter is engineered for precision metalworking tasks. Made from high-speed steel, this conical bit resists wear and tolerates elevated temperatures produced during drilling. It is intended for creating conical holes, countersinking, or enlarging existing holes in steel and a variety of ferrous and non-ferrous metals in workshop and maintenance environments.

Advantages

The HSS material provides a balance of hardness and toughness for reliable cutting performance and extended service life under typical machining conditions. The conical geometry enables progressive material removal for clean countersinks and tapered hole profiles while reducing the tendency to grab or chatter. Its single-piece design offers consistent concentricity and easier alignment in handheld or machine-mounted setups.

Suitable for

• Creating conical holes for fastener seating and countersinking in metal components
• Enlarging or reaming existing holes to a tapered profile
• Workshop maintenance, metal fabrication, and general repair tasks
• Use with drill presses, lathes, and suitable handheld drills when proper clamps and speeds are applied

Key specifications

• Cutting diameter: 14.5 mm
• Material: high-speed steel (HSS)
• Geometry: conical/tapered cutting profile for countersinking and tapered holes
• Intended use: drilling and countersinking in ferrous and non-ferrous metals
• Typical applications: workshop and maintenance metalworking

How to use

Secure the workpiece firmly to prevent movement, select an appropriate spindle speed for the material and bit diameter, and apply steady feed pressure. Use cutting fluid or coolant when working with steel to reduce heat and prolong tool life. Start with a pilot hole if accuracy is critical, then advance the conical bit gradually to achieve the desired taper or countersink depth. Clear chips regularly to avoid clogging and overheating.

Usage recommendations

For best results, match drill speed and lubricant to the metal being worked: lower speeds for harder steels, higher speeds for softer non-ferrous alloys. Inspect the cutting edges before use and replace the bit when wear compromises cutting quality. When using handheld drills, maintain firm control and appropriate clamping; when possible, prefer machine-mounted operation for higher precision.
