Reamer Abraboro AB91030165 HSS-G 3.2–16.5 mm cutting diameter, 60 mm length

The Abraboro AB91030165 HSS-G reamer is a solid high-speed steel tool with an adjustable cutting diameter ranging from 3.2 to 16.5 mm and an overall length of 60 mm. Intended for precision enlarging and finishing of drilled holes in metalworking, the reamer is suitable for both manual and machine applications. Its stepped, variable sizing allows progressive material removal to achieve accurate hole diameter and improved surface finish without introducing identifiers or accessory parts.

Advantages

This HSS-G reamer offers consistent concentricity and dimensional accuracy across its adjustable range, enabling tight tolerance results in a single operation. The high-speed steel construction provides wear resistance and heat tolerance appropriate for a variety of ferrous and non-ferrous metals. The stepped/variable design reduces the need for multiple fixed-size reamers, saving setup time and tool changes while maintaining a fine surface finish.

Suitable for

• Enlarging and finishing drilled holes in steel, aluminum and other metals
• Machine reaming operations on lathes, milling machines or drill presses
• Manual reaming where adjustable diameter is required
• Prototyping and small-batch production requiring accurate hole sizing

Key specifications

• Material: high-speed steel (HSS-G)
• Cutting diameter: adjustable from 3.2 mm to 16.5 mm
• Overall length: 60 mm
• Design: solid, stepped/variable reamer profile for progressive cutting
• Application: suitable for manual and machine use

How to use

Select the reamer and secure it in the appropriate machine spindle or manual handle. Ensure the workpiece hole is pre-drilled to a size slightly smaller than the target diameter to allow the reamer to cut progressively. Use proper cutting fluid compatible with the material being machined to reduce heat and improve surface finish. Apply steady feed and rotation speed within typical reaming parameters for HSS tools; do not force the tool and withdraw periodically to clear chips when machining deeper holes.

Usage recommendations

For best results, match the pre-drill size to the midpoint of the reamer's cutting range for the intended final diameter, maintain consistent coolant flow, and inspect finished holes with appropriate measuring instruments. Avoid excessive speeds that may overheat the HSS material and shorten tool life.
