Adjustable HSS Reamer GEKO G38263 15.25–17 mm, pack of 100

Adjustable HSS Reamer GEKO G38263 15.25–17 mm, pack of 100 is a set of precision cutting tools made from high-speed steel for controlled material removal and accurate hole sizing. Designed for finishing drilled holes, each adjustable reamer covers a diameter range of 15.25 to 17 mm, allowing fine adjustment to obtain required tolerances. Supplied in a pack of 100, the reamers are intended for repetitive workshop use in metalworking and mechanical maintenance environments where consistent hole dimensions are needed.

Advantages

The high-speed steel construction provides durability and resistance to wear during repeated reaming operations, ensuring a stable cutting edge. The adjustable design permits incremental diameter adjustment within the specified range, reducing the need for multiple fixed-size tools. A consistent geometry and quality control in production support predictable performance and repeatable results when used with appropriate speeds and feeds.

Suitable for

• Finishing drilled holes in steel and non-ferrous metals
• Workshop and production reaming tasks requiring accurate hole diameters
• Mechanical maintenance and assembly where hole fit and alignment are important
• Batch operations where tool interchangeability and repeatability are needed

Key specifications

• Material: high-speed steel (HSS)
• Adjustable diameter range: 15.25–17.00 mm
• Shank type: straight cylindrical shank suitable for standard chucks and collets
• Pack quantity: 100 reamers per pack
• Intended use: precision reaming/finishing of pre-drilled holes

How to use

Select a reamer and set the adjustable cutting diameter within the 15.25–17.00 mm range according to the required finished hole size and tolerance. Secure the reamer in a suitable chuck or collet and ensure the workpiece is rigidly clamped. Use appropriate cutting speed, feed and cutting fluid for the work material to maintain tool life and surface finish. Advance the reamer steadily through the pilot hole without excessive lateral force, then retract carefully to avoid scoring the finished bore.

Usage recommendations

For best results, pre-drill holes to an appropriate undersize so the adjustable reamer performs finishing cuts rather than heavy stock removal. Use coolant or cutting fluid when reaming steels to reduce heat and improve surface finish. Inspect reamers periodically for wear; replace worn tools to maintain dimensional accuracy. Match cutting parameters to material type and machine rigidity to achieve consistent bore tolerances.
