TECWERK Hand Reamer DIN 206 H7, 22 mm, HSS, Spiral-Fluted

The TECWERK Hand Reamer DIN 206 H7, 22 mm is a precision finishing tool designed for producing accurate bores to H7 tolerance in metalworking and toolroom applications.

• HSS construction for durable cutting
• DIN 206 Form B with H7 tolerance
• Spiral-fluted design for reliable chip flow

Consistent bore quality for dependable assemblies

The spiral-fluted finishing tool is manufactured from HSS and specified to DIN 206, which together provide a balance of toughness and wear resistance suited to hand reaming operations. The combination of Form B geometry and H7 tolerance supports consistent diametral accuracy, reducing the need for downstream machining or adjustment. For production runs where repeatable hole size and surface conformity matter, this reamer maintains the finished bore within the expected tolerance band and minimises scrap caused by undersize or oversize bores.

Efficient chip evacuation and smoother cutting action

The spiral-fluted design promotes controlled chip evacuation, directing chips away from the cutting edge and the workpiece for cleaner finishes. The flute helix and long lead reduce re-cutting of chips and lessen the risk of chatter, which benefits both hole roundness and surface quality. In practice, these features mean fewer interruptions for clearing and a steadier feed during manual reaming, translating into higher throughput for small-batch machining and maintenance tasks.

Secure mounting and simplified handling for workshop use

Equipped with a cylindrical shank and integrated square drive, the tool allows straightforward clamping in hand-tool holders or tailstock chucks while providing a positive means for torque transfer and withdrawal control. The long lead facilitates gradual engagement with the bore, easing alignment and promoting concentricity during manual operation. These handling advantages reduce setup time and contribute to more uniform results for skilled operators and experienced craftspersons alike.

Clear technical choice for diverse metalworking tasks

Specified as a right-hand cutting tool with a spiral helix, this reamer is intended for standard clockwise reaming operations while the flute geometry aids smooth chip flow. The uncoated HSS construction is suitable where toughness and a clean cutting edge are priorities, and it can be re-sharpened by specialist toolmakers to extend service life. For customers evaluating tooling options, the reamer represents a pragmatic choice when precision finishing to ISO tolerance classes is required without resorting to powered reaming equipment.

FAQ

What tolerance does this reamer achieve?
The TECWERK hand reamer is manufactured to H7 tolerance under the DIN 206 specification, making it suitable for standard precision fits and repeatable bore finishing.

Which materials is the reamer suitable for?
The tool is made of HSS, offering a compromise between toughness and wear resistance for conventional metalworking materials; suitability depends on the specific workpiece alloy and cutting conditions.

How should the reamer be clamped for best results?
Use the cylindrical shank in an appropriate hand-holder or chuck and employ the square drive for controlled rotation and retraction; steady feed and proper alignment yield the best concentricity.

Can the reamer be re-sharpened?
Yes. The HSS construction supports re-sharpening by a qualified tool-service provider to restore cutting edges and extend service life.

Is this product suitable for powered reaming machines?
Although primarily designed as a hand reamer, the cylindrical shank and square drive permit mounting in suitable fixtures; verify machine compatibility and operational parameters before use.
