NC machine reamer DIN 212-3 H7 Form B, Ø 13 mm — HSS‑Co (TECWERK)

The NC machine reamer DIN 212-3 H7 Form B, Ø 13 mm, HSS‑Co is a production-grade reaming tool designed for finishing accurate fits in steel, GGG and non‑ferrous metals in NC machining environments.

• HSS‑Co high‑speed steel substrate
• Tolerance H7 for precision fits
• Cylindrical shank for secure clamping
• Suitable for steel, GGG and non‑ferrous metals

Consistent production tolerances for reliable assemblies

Designed to meet industrial machining demands, this reamer combines a DIN 212‑3 geometry with a Form B profile to deliver repeatable fitting results. The HSS‑Co alloy improves heat resistance compared with standard high‑speed steels, reducing wear in continuous operations. By using a tool with H7 tolerance, shops can achieve common clearance and transition fits without additional testing, which reduces rework and stabilises assembly processes. The combination of geometry and material results in a tool that supports a predictable process window and lowers scrap rates in batch production.

Material compatibility and application advantages

The cutter is optimised for finishing through and blind holes in a range of workpiece materials, explicitly including steel, GGG (spheroidal graphite cast iron) and non‑ferrous alloys. The flute design and cutting geometry are selected to manage chip evacuation and surface integrity, so the machined bore retains dimensional accuracy and a smooth surface finish. For manufacturers producing mating parts, this means fewer downstream adjustments and fewer rejected assemblies, improving overall throughput and customer confidence in part interchangeability.

Clamping, runout and process security

A secure hold is essential to exploit the tool’s capability for runout accuracy. The reamer’s cylindrical shank is intended for use with hydraulic collets, high‑accuracy chucks or shrink fit holders; when paired with such holders, the tool achieves the roundness and concentricity required for precision fits. The tool features helical flutes and an unequal spacing pattern that helps reduce vibration and harmonics during rotation, contributing to stable cutting conditions. These design choices translate into reduced tool chatter, longer tool life and a more reliable process window on CNC machines.

Practical benefits for workshop and production environments

The tool’s construction and geometry focus on minimising interruptions in workflow. Right‑hand cutting action combined with the specified helix direction supports consistent chip flow for typical machining setups. For operations where fixture and spindle stability vary, the reamer’s robustness and material selection offer better resistance to thermal softening and wear than plain high‑speed steels. This resilience supports higher uptime, less frequent tool changes and a clearer planning horizon for maintenance intervals, which is particularly valuable for subcontractors and medium‑volume production facilities.

FAQ

What tolerance class does this reamer achieve?
The NC machine reamer DIN 212‑3 H7 Form B, Ø 13 mm (TECWERK, SKU 2000865314NW) is manufactured to deliver an H7 tolerance, suitable for standard precision fits in production parts.

Which materials can be machined with this reamer?
This reamer is specified for finishing holes in steel, GGG (spheroidal graphite cast iron) and non‑ferrous metals, making it versatile for common engineering materials.

How should the tool be clamped for best results?
For optimal runout accuracy and process security, use a hydraulic collet, high‑accuracy chuck or shrink fit holder; these clamping methods complement the reamer’s cylindrical shank and reduce spindle‑tool eccentricity.

Is the reamer suitable for both through and blind holes?
Yes, the design supports machining of both through and blind holes, with flute geometry intended to manage chip evacuation and surface finish accordingly.

What advantages does the HSS‑Co material provide?
The HSS‑Co alloy enhances heat resistance and wear performance compared with standard high‑speed steels, improving tool life and stability during longer production runs.
