Drill bit Abraboro HSS conical 23.0 mm AB44523000 for metal

Conical HSS drill bit Abraboro 23.0 mm AB44523000 is designed for drilling metal with controlled material removal and accurate hole shaping. Manufactured from high-speed steel (HSS), the conical geometry allows progressive diameter increase in a single pass, reducing stress on the workpiece and improving centring when used with drill presses or hand drills. The tool is intended for workshop and industrial maintenance applications where a precise conical hole or step is required.

Advantages

The HSS material provides good wear resistance and heat tolerance for metalworking operations, ensuring consistent performance under elevated temperatures. The conical shape enables gradual cutting action, which reduces tendency to grab and improves surface finish compared with abrupt diameter changes. The drill bit’s geometry supports accurate alignment and smooth chip evacuation when used with proper speeds and lubrication, contributing to longer tool life and predictable hole dimensions.

Suitable for

• Drilling conical or stepped holes in steel and non-ferrous metals
• Workshop and maintenance tasks with drill presses
• Hand-held drilling where progressive diameter control is needed
• Preparing holes for countersinking or for assembly requiring tapered fits

Key specifications

• Material: high-speed steel (HSS)
• Type: conical (tapered) drill bit
• Nominal diameter: 23.0 mm
• Intended application: metal drilling
• Compatibility: suitable for drill presses and hand drills

How to use

Secure the workpiece firmly and select appropriate rotational speed according to the metal type and thickness. Mount the conical HSS bit in the drill chuck ensuring correct centring and runout under control. Use cutting fluid or suitable coolant to reduce heat and improve chip evacuation when drilling metals. Apply steady, moderate feed pressure and allow the conical geometry to progressively enlarge the hole; avoid excessive force that can cause bit bending or workpiece distortion. Clear chips regularly and inspect hole dimensions as you approach the final diameter.

Usage recommendations

For best results, use lower speeds and consistent cutting fluid when drilling hard steels; higher speeds can be used for softer non-ferrous alloys. Check chuck runout before use and replace the bit if cutting performance or concentricity degrades.
