Machine reamer DIN 8094 H7 Form B, 12 mm (HM, MK1) – TECWERK

The TECWERK machine reamer is a Form B reamer manufactured to DIN 8094, designed for precision finishing of 12 mm holes in a range of engineering materials

• Carbide tip for extended tool life
• DIN 8094 standardised cutting geometry
• H7 tolerance for repeatable fits
• Morse taper MK1 shank for rigid mounting

Consistent hole tolerances for reliable assembly

The reamer follows DIN 8094 and is specified to achieve H7 tolerance, providing machining results that match common industrial fitting standards. This standardised geometry reduces variation between batches, so components slide together with consistent clearance and assembly times fall. The combination of standard conformity and tight tolerance control helps to lower scrap rates and rework, supporting a steadier production flow and fewer inspection interventions.

Robust carbide cutting and optimised flute design

Equipped with a HM (carbide) cutting body and helical flutes, the tool delivers durable edge retention and effective chip evacuation when finishing internal diameters. The listed geometry—right-hand cutting with left-hand spiral flutes—promotes stable cutting forces and improved surface finish in mixed-material applications. The specification includes suitability for steel, GGG (ductile cast iron) and non‑ferrous metals, which allows one tool to cover common workshop requirements while maintaining surface integrity and dimensional accuracy.

Secure mounting and process stability on machine tools

The Morse taper MK1 shank ensures rigid seating and simple mounting in compatible spindles or holders, minimising run-out and vibration during reaming operations. Stable clamping improves roundness and concentricity, which is especially beneficial when finishing bores destined for bearings, dowels or fitted assemblies. For workshop planners and toolroom engineers, this results in fewer rejects and a predictable machining step in multi-stage production lines; Metav Werkzeuge’s consultants can advise on holder compatibility and best practice integration.

FAQ

Which materials is the reamer suitable for?
The TECWERK machine reamer is suitable for steel, GGG (ductile cast iron) and non‑ferrous metals as stated in the product specification.

What tolerance can be expected from this reamer?
The tool is manufactured to deliver an H7 tolerance in accordance with DIN 8094 for consistent, standardised fits.

What shank type does the tool use and how is it mounted?
This reamer is supplied with an MK1 (Morse taper 1) shank for direct mounting in compatible spindles or taper holders.

Is the cutting material carbide or HSS?
The designation HM indicates a carbide cutting material, giving enhanced wear resistance compared with high-speed steel.

Does the tool comply with an industrial standard?
Yes, the reamer is produced to DIN 8094 and specified as Form B for standardised reaming geometry.
