Take advantage of a combination of HSS durability, precise H7 tolerance and spiral-fluted geometry for reliable finishing of pre-bored holes; order supply and consultancy via Metav Werkzeuge for streamlined procurement and rapid delivery from Emmerich.

Hand reamer DIN 206 H7 Form B, 18 mm, HSS, spiral-fluted — TECWERK

The Hand reamer DIN 206 H7 Form B, 18 mm, HSS, spiral-fluted is a manual finishing tool designed for producing tight tolerance bores in workshop and light industrial environments.

• HSS for long tool life and edge retention
• DIN 206 Form B — tolerance H7
• Spiral-fluted for smooth chip evacuation
• Cylindrical shank with square end

Consistent bore tolerances for assembly-ready parts

This tool is engineered to meet DIN 206 specification and to produce holes to H7 tolerance, delivering fit accuracy that reduces rework and speeds assembly. The standardised form ensures interchangeability with mating parts and simplifies quality control routines; when pre-bored holes are finished with the correct tolerance band, subsequent processes such as press fits or bearing installations proceed without additional machining. The focus on measurable precision supports predictable production yields and lowers scrap rates, making the finishing operation both reliable and economically beneficial.

Geometry and material for steady cutting performance

Constructed from HSS and configured as a spiral-fluted reamer, the tool provides a balance of toughness and sharpness that resists edge chipping during manual use. The spiral flutes promote consistent chip evacuation, improving surface finish and reducing the risk of clogging in interrupted cuts. The chosen cutting geometry supports smooth entry and exit, which in turn helps maintain concentricity and minimises burr formation. These characteristics are particularly useful for finishing steels and general engineering materials where a controlled, clean cut is required.

Practical handling and secure clamping for workshop use

A cylindrical shank with square end provides secure clamping in bench holders or tailstocks and allows torque to be applied without slippage. The tool’s long cutting entry offers progressive engagement that eases manual feed and improves user control, which is valuable when reproducing consistent results across multiple components. The uncoated tool surface simplifies re-sharpening when required and avoids incompatibilities with coating-sensitive operations, while the solid construction supports repeatable manual finishing tasks across varied production batches.

Where this reamer adds value in daily operations

By combining standard conformity with robust material choice and flute design, the reamer reduces cycle variability and supports lean workshop practices. The tool is suitable for maintenance shops, prototyping facilities and small-batch production where manual finishing remains efficient; consistent hole quality shortens assembly time and reduces inspection burdens. For procurement, specifying a tool that meets recognised standards streamlines supplier audits and ensures compatibility across diverse equipment fleets, reinforcing dependable supply and operational continuity.
