Drill bit Abraboro HSS conical 32.0 mm AB44532000

Abraboro HSS conical 32.0 mm AB44532000 is a high-speed steel conical drill bit designed for cutting, enlarging and chamfering holes in metal and other suitable materials. The tapered geometry provides a gradual cutting profile that is useful for deburring, preparing stepped holes and producing chamfers without the need for multiple tools. The tool is suitable for operation in hand drills and drill presses where controlled material removal and a conical finish are required.

Advantages

The HSS construction ensures good wear resistance and heat tolerance during conventional drilling and light cutting operations. The conical shape allows progressive material engagement for smoother cuts and reduced risk of snagging compared with abrupt step cutters. Its single-tool conical profile reduces tool changes when forming tapered entries, chamfers or when deburring the edges of drilled holes.

Suitable for

• Chamfering and deburring holes in steel and non-ferrous metals
• Enlarging or tapering existing holes
• Preparing stepped or countersunk entries for fasteners
• Use in hand drills and bench drill presses for controlled finishing

Key specifications

• Material: High-speed steel (HSS)
• Shape: Conical / tapered cutting profile
• Diameter: 32.0 mm cutting diameter
• Primary use: Cutting, chamfering, deburring and hole enlargement
• Suitable machines: Hand drills and drill presses

How to use

Secure the workpiece and select a suitable drilling speed for HSS tools and the work material. Fit the conical bit in the drill chuck ensuring it is clamped firmly and runs true. Approach the hole steadily with light to moderate feed pressure; allow the conical profile to cut progressively rather than forcing rapid penetration. Withdraw the bit periodically to clear chips and inspect the chamfer or taper until the desired profile and edge finish are achieved.

Usage recommendations

Use cutting lubricant or coolant when working with steel to reduce heat and improve tool life. Start at a lower speed for larger diameters and increase only if cut quality permits. Always wear appropriate eye protection and follow machine safety procedures.
