NC machine reamer DIN 212‑3 H7 Form B, 15 mm — TECWERK HSS‑Co

The NC machine reamer DIN 212‑3 H7 Form B, 15 mm is a high‑precision finishing tool for CNC operations, developed for reliable bore sizing and surface quality in through and blind holes across a range of metallic substrates.

• HSS‑Co material for high wear resistance
• Tolerance H7 for precision fits
• Spiral flutes with left‑hand helix
• Cylinder shank with unequal pitch

Consistent bore tolerances for fit‑critical assemblies

The reamer delivers repeatable results by combining a tolerance H7 specification with a hard‑wearing HSS‑Co composition, ensuring that final bores meet standardised fits with minimal rework. The controlled cutting geometry reduces dimensional deviation, which supports tighter assembly tolerances and predictable interchangeability of mating components. This level of precision benefits production processes where component fit is critical and quality control must be reliably reproducible.

Durable performance across common engineering materials

Manufactured from cobalt‑alloyed high‑speed steel, the tool copes well with a spectrum of materials including steel, grey and ductile cast irons and non‑ferrous metals. The choice of HSS‑Co balances toughness and red‑hardness resistance, extending tool life under intermittent CNC spindle loads and in applications where heat generation is significant. As a result, maintenance intervals are lengthened and overall process efficiency is improved without compromising finish quality.

Geometry engineered to minimise runout and chatter

The flute design features spiral flutes with a left‑hand helix and unequal pitch, which together disrupt harmonic vibrations and distribute cutting forces more evenly. The cylinder shank assists in stable clamping, while the tool’s profile produces a controlled chip flow suitable for both blind and through bores. When used with precision holding systems such as hydro expansion or high‑accuracy shrink chucks, the reamer contributes to exceptionally low runout accuracy, supporting higher production speeds with consistent surface finish.

Ready integration into CNC workflows for reliable throughput

Designed to the DIN 212‑3 standard and configured as Form B, the reamer is compatible with typical NC machining cycles for finishing operations. Its right‑hand cutting direction and shank form permit straightforward use in automated tool magazines and enable predictable toolpath programming. The tool’s characteristics favour process security in serial production: fewer rejects, lower rework rates and better overall machining economy when integrated into a coherent tooling strategy.

FAQ

What hole sizes does this reamer produce to tolerance?
The TECWERK NC machine reamer DIN 212‑3 H7 Form B, 15 mm produces bores to H7 tolerance for a 15 mm nominal size, suitable for fit‑critical applications.

Can this reamer be used on cast iron and aluminium?
Yes — the tool is specified for use on steel, GGG (cast iron) and non‑ferrous metals, including aluminium alloys.

Which shank type is fitted and how does it aid clamping?
The reamer features a cylinder shank, which is compatible with common chucks and supports secure clamping for improved concentricity.

Is the geometry suited to blind holes as well as through holes?
The design addresses both through and blind holes, with flute geometry optimised to control chip evacuation and finish quality in both cases.

Are special chucks recommended to achieve best runout results?
For maximum runout accuracy, pairing the reamer with hydro expansion, high‑precision shrink or high‑accuracy collet chucks is recommended to reduce eccentricity during machining.
