Cone Reamer Abraboro HSS-Co 3.2–16.5 mm 60 mm working length

The Abraboro Cone Reamer HSS-Co 3.2–16.5 mm with a 60 mm working length is a high-speed steel cobalt reamer designed to enlarge, finish or deburr holes with a continuously variable diameter between 3.2 and 16.5 mm. Built for use by hand or with a machine, this cone reamer produces smooth, concentric hole profiles in metals and compatible materials. It is intended for tasks that require accurate hole sizing and clean internal edges without changing the basic geometry of the workpiece.

Advantages

This Abraboro cone reamer combines the wear resistance of HSS-Co material with a tapered geometry that enables gradual enlargement and precision finishing of holes. The continuous diameter range removes the need for multiple fixed-diameter reamers, while the 60 mm working length provides access to deeper hole sections. The tool’s design supports both manual operation and machine-mounted use, offering consistent concentricity and reduced burr formation when used with appropriate speeds and lubrication.

Suitable for (tasks / use cases)

• Deburring and enlarging drilled holes in steel and non-ferrous metals
• Precision fit adjustments in assembly and fitting operations
• Toolmaking and maintenance tasks requiring smooth internal finishes
• Field or workshop use where one adjustable tool replaces several fixed-size reamers

Key specifications

• Material: High-speed steel with cobalt (HSS-Co)
• Diameter range: 3.2 mm to 16.5 mm (continuously variable)
• Working length: 60 mm
• Geometry: Conical cutting profile for progressive material removal
• Mounting: Suitable for manual use or machine holders compatible with conical shank tooling

How to use

Select appropriate rotational speed and cutting fluid for the workpiece material to reduce heat and extend tool life. Secure the workpiece and ensure the reamer is aligned with the hole axis before advancing the tool. For manual use, apply steady, even pressure and withdraw frequently to clear chips. For machine use, feed the tool at a controlled rate to achieve the desired diameter and finish, and back off periodically if chip evacuation is restricted. Inspect the hole after finishing and make any incremental passes as required to reach the exact size.

Usage recommendations

Use cutting oil or coolant when working on steels and harder alloys, and choose lower speeds for tougher materials. Maintain proper alignment to preserve concentricity and avoid side loading. Replace the tool if wear or chipping is observed to maintain hole quality.
