Adjustable HSS Reamer GEKO G38264 17–19 mm, pack of 100

Adjustable HSS Reamer GEKO G38264 17–19 mm, pack of 100 is a set of precision adjustable reamers designed for finishing and slightly enlarging drilled holes in metal and similar materials. Manufactured from high-speed steel (HSS), each tool provides wear resistance and consistent cutting performance across repeated use. The adjustable range of 17–19 mm allows adaptation to close tolerance sizes without the need for multiple fixed reamers, while the bulk packaging of 100 pieces supports series production or workshop stocking.

Advantages

This adjustable HSS reamer offers precise material removal and a reliable surface finish due to its high-speed steel construction. The adjustable cutting diameter reduces the number of individual tools required, and the robust HSS material ensures durability under both hand-held and machine-mounted operation. Supplied in a pack of 100, the set is convenient for production environments and maintenance teams needing consistent, repeatable performance.

Suitable for

• Finishing and sizing drilled holes in steel, cast iron and similar metals
• Workshop and production-line reaming tasks requiring adjustable diameter
• Maintenance and repair operations where multiple identical tools are needed
• Use in hand-held tools or machine-mounted setups (light milling or drilling machines)

Key specifications

• Material: high-speed steel (HSS)
• Adjustable diameter range: 17–19 mm
• Quantity in pack: 100 pieces
• Intended use: finishing and enlargement of drilled holes
• Compatibility: suitable for hand-held and machine-mounted reaming operations

How to use

Secure the workpiece and ensure the drilled hole is free of chips and burrs before reaming. Fit the adjustable HSS reamer into the appropriate tool holder or chuck, set the cutting diameter within the 17–19 mm range according to the required tolerance, and verify alignment with the hole axis. Apply steady feed and moderate cutting speed appropriate for the work material, using cutting fluid where recommended to improve finish and tool life. After reaming, clean the hole and inspect dimensions and surface finish with suitable gauges.

Usage recommendations

For best results, use cutting fluid with ferrous materials and avoid excessive feed or speed to preserve reamer geometry. Store tools in a dry place and inspect cutting edges periodically; replace or re-sharpen if wear affects hole quality. When consistent diameter is critical, measure tools and test on scrap material before final use.
