Handreibahle DIN 206 H7 Form B D.4mm HSS drallgenutet TECWERK — Hand reamer, 4 mm, HSS, spiral-fluted, Form B

The Handreibahle DIN 206 H7 Form B D.4mm HSS drallgenutet TECWERK is a spiral-fluted hand reamer designed for finishing precision holes to H7 tolerance under the DIN 206 standard, suited to workshop and light industrial reaming tasks

• DIN 206, Form B, tolerance H7
• HSS cutting material, re-sharpenable
• Spiral-fluted for improved chip control
• Cylindrical shank with square end

Accurate finishing that meets standard tolerances

The reamer follows DIN 206 and is manufactured to a H7 tolerance, which guarantees repeatable hole sizes for assembly-critical parts. The tool is made from HSS, offering a balance between toughness and edge retention; this means the cutting edge withstands routine workshop use and can be re-sharpened when necessary, extending service life. For planners and buyers this translates into predictable part interchangeability and reduced scrap rates, supporting smoother production flows and quality assurance processes.

Improved surface quality and chip evacuation for consistent results

The spiral-fluted design promotes reliable chip evacuation and helps to produce a refined bore surface with minimal scoring. The combination of left-hand helix and right-hand cutting geometry supports controlled cutting action and helps to avoid chatter in manual reaming operations, particularly with longer engagement lengths. The long cutting length provides greater reach in deeper holes while maintaining finish quality, reducing the need for additional tooling steps and saving time on repetitive finishing tasks.

Practical mounting and simple integration into workshop tooling

A cylindrical shank and square end allow flexible mounting: the cylindrical portion fits standard chucks while the square enables secure drive in manual handles or suitable arbors. The reamer is uncoated, making it straightforward to recondition, and its HSS composition is compatible with conventional sharpening practices. This practical design reduces tool-change complexity and supports immediate integration into existing tool sets, making it suitable for service engineers, maintenance teams and production operators who require dependable reaming with minimal setup.
