Reamer Abraboro HSS-G AB91030083 Ø2.0–8.3 mm shank 50 mm

Solid high-speed steel adjustable reamer Abraboro AB91030083 with a cutting diameter range of 2.0–8.3 mm and a 50 mm shank length. This tool is designed for enlarging and finishing drilled holes to precise diameters in metalworking and machining operations. The HSS-G material offers hardness and wear resistance suitable for machining steel and many other common metals. The reamer fits standard drilling machines and machine tools where consistent hole tolerance and improved surface finish are required.

Advantages

The adjustable design covers a wide diameter range, reducing the need to change tools for small incremental sizes. Manufactured from high-speed steel, the reamer provides good cutting edge retention and durability under typical drilling and reaming speeds. Its solid construction and 50 mm shank ensure secure clamping in machine chucks and tool holders, while the fine cutting geometry contributes to accurate hole sizing and improved surface finish without additional deburring steps.

Suitable for

• Enlarging and finishing holes in steel components
• Precision reaming tasks on milling machines and drill presses
• Repair and maintenance operations requiring accurate hole repair
• Small-batch production where flexibility across diameters is needed

Key specifications

• Material: High-speed steel (HSS-G)
• Adjustable cutting diameter: 2.0–8.3 mm
• Shank length: 50 mm
• Tool type: Solid adjustable reamer
• Intended use: Hole finishing and sizing in metalworking

How to use

Mount the reamer securely in the drill chuck or tool holder ensuring the 50 mm shank is clamped firmly and concentric. Pre-drill the hole to a size slightly smaller than the target diameter, following recommended pilot drill sizes for the material being processed. Run the machine at appropriate spindle speed for HSS tooling, apply steady feed without excessive axial force, and use cutting fluid suitable for the workpiece material to improve surface finish and tool life. Make incremental passes and check diameter with a gauge until the required tolerance is achieved.

Usage recommendations

For best results use light, consistent feed and moderate speeds for ferrous materials; employ appropriate cutting fluid to reduce heat and prolong tool life. Avoid excessive side load and ensure the workpiece is rigidly fixtured to maintain concentricity and dimensional accuracy.
