Adjustable HSS Reamer GEKO 19–21 mm G38265, pack 50/100

Adjustable HSS Reamer GEKO 19–21 mm G38265 is a precision cutting tool designed for enlarging and finishing drilled holes to precise diameters. Manufactured from high-speed steel (HSS), this reamer provides consistent cutting performance and wear resistance for use on steel and non-ferrous metals. The reamer’s adjustable cutting diameter range of 19–21 mm allows for fine tuning to achieve accurate fits and tight tolerances in workshop and industrial applications. Pack options are indicated as 50/100 units.

Advantages

The adjustable design permits gradual diameter adjustment within the 19–21 mm range, reducing the need for multiple fixed-size reamers. HSS construction offers a balance of toughness and heat resistance for sustained cutting performance. The tool is suitable for producing smooth, concentric holes with minimal burrs and predictable dimensional outcomes. Its compatibility with common drilling and reaming setups makes it practical for both maintenance and production environments.

Suitable for

• Finishing and sizing holes in steel components
• Working with non-ferrous metals such as aluminum and brass
• Preparing holes for press fits, dowels, or bearings
• Deburring and improving hole surface quality after drilling
• Workshop, maintenance, and light industrial production tasks

How to use

Select the reamer and set the cutting diameter within the 19–21 mm range according to the target hole size, following the manufacturer's adjustment procedure. Secure the workpiece and ensure the existing hole is centered and free of heavy burrs. Use appropriate cutting fluid for the workpiece material to reduce heat and prolong tool life. Operate at recommended spindle speeds and feed rates for HSS cutting on the specific material; apply steady axial pressure and avoid excessive side load. After reaming, measure the hole diameter and surface finish, and make fine adjustments if necessary.

Usage recommendations

For best results, use cutting fluid when reaming steel and maintain proper spindle alignment. Inspect cutting edges before use and replace or recondition the tool if wear affects concentricity or surface finish. Store the reamers in a dry, protected case to prevent damage and corrosion.
