Abraboro HSS Metal Cone Drill 17.5 mm AB44517500

The Abraboro HSS Metal Cone Drill 17.5 mm AB44517500 is a high-speed steel cone-shaped drill designed for drilling, enlarging and chamfering holes in ferrous and non-ferrous metals. Its tapered profile enables stepped hole creation and precise deburring in a single operation, making it suitable for workshop, maintenance and fabrication environments where controlled hole sizing and edge finishing are required.

Advantages

Constructed from high-speed steel, the cone drill offers durability and wear resistance during repeated use in metalworking applications. The conical geometry provides gradual material removal and accurate control over hole diameter, while the single-flute design reduces clogging and improves chip evacuation. Its versatility allows drilling, reaming and chamfering with one tool, reducing tool changes and setup time.

Suitable for

• Drilling and enlarging holes in steel and stainless steel
• Deburring and chamfering hole edges
• Workshop maintenance and metal fabrication tasks
• Prototype work and small-batch production requiring variable hole sizes

Key specifications

• Material: high-speed steel (HSS)
• Shape: conical / stepped drill
• Maximum diameter: 17.5 mm
• Intended materials: ferrous and non-ferrous metals
• Primary functions: drilling, enlarging, deburring/chamfering

How to use

Select a suitable spindle speed and steady feed rate according to the workpiece material and thickness; use cutting fluid for improved finish and tool life when machining steels. Clamp the workpiece securely and align the drill with the intended hole position. Start cutting with light pressure, increasing gradually as the cone advances to the desired diameter. Retract periodically to clear chips if machining thick sections or heavy material. For chamfering, advance until the desired edge break or chamfer width is achieved.

Usage recommendations

Use appropriate personal protective equipment and secure clamping. For stainless steels and harder alloys, reduce cutting speed and ensure adequate lubrication. Inspect the cutting edge for wear and replace the tool when performance degrades to maintain hole accuracy and surface quality.
