Drill bit Abraboro HSS conical for metal 19 mm AB44519000

The Abraboro HSS conical drill bit 19 mm AB44519000 is designed for drilling and enlarging holes in metal. Manufactured from high-speed steel (HSS), this conical bit offers heat resistance and wear tolerance needed for metalworking operations. Its tapered geometry allows progressive hole enlargement, step drilling and light deburring in a single tool, and it is compatible with both handheld drills and drill presses used in workshops, maintenance and fabrication tasks.

Advantages

The conical shape provides smooth, incremental cutting action that reduces the risk of catching and minimizes material stress. High-speed steel construction ensures durability and maintains cutting performance under elevated temperatures common in metal drilling. The single-tool design combines drilling and chamfering capabilities, reducing tool changes and improving efficiency in repetitive tasks. The 19 mm diameter is suited for medium-sized holes frequently required in metal assembly and repair work.

Suitable for

• Drilling and enlarging holes in mild steel, stainless steel and non-ferrous metals
• Workshop and maintenance tasks using hand drills or drill presses
• Fabrication and fitting where progressive hole sizing or deburring is needed

Key specifications

• Material: high-speed steel (HSS)
• Geometry: conical / tapered
• Nominal diameter: 19 mm
• Primary applications: drilling, progressive hole enlargement, light deburring
• Compatibility: suitable for hand-held drills and drill presses

How to use

Secure the workpiece firmly and select appropriate clamping to prevent movement. Fit the conical HSS bit into the drill chuck and ensure it is tightly clamped and correctly centered. Start drilling at low speed to establish the initial contact, then increase speed according to material and machine recommendations while applying steady, moderate pressure. For incremental enlargement, advance the bit slowly to allow the conical geometry to cut progressively. Withdraw occasionally to clear chips and avoid overheating. After use, clean chips from the flutes and store the bit in a protective case or holder.

Usage recommendations

Use cutting fluid or lubricant when drilling harder metals to extend tool life and improve surface finish. Match drill speed and feed to the metal type: lower speeds for stainless steel and higher speeds for softer, non-ferrous metals. Replace the bit when signs of excessive wear, chipping or rounded cutting edges appear to maintain hole quality and reduce workpiece damage.
