TECWERK Machine Reamer DIN 8093 H7, 11 mm, Carbide (Form B)

TECWERK Machine Reamer DIN 8093 H7 is a carbide finishing tool for precision hole preparation in steel, GGG and non‑ferrous metals, designed to meet DIN 8093 Form B requirements.

• DIN 8093, Form B compliance
• H7 tolerance for precision fits
• Carbide cutting edges for extended life
• Left‑hand spiral flutes for chip control
• Cylindrical shank, tolerance h6 from 10 mm

Consistent hole quality through defined tolerances

The reamer is engineered to produce H7 hole tolerances, which translates into reliable clearance and repeatable fits in assembly operations. A tool specified to DIN 8093 ensures that geometry and finish are consistent with industrial standards; this reduces rework and inspection time and supports predictable assembly behaviour. Where tight mating fits are required, the documented tolerance class provides measurable assurance of final dimensions.

Durable cutting system for mixed materials

Equipped with HM (carbide) cutting plates, the tool combines wear resistance with edge stability for extended tool life when machining steel, GGG (ductile iron) and non‑ferrous metals. Carbide cutting edges maintain form under load, offering a stable cutting geometry that preserves hole roundness and surface finish. The material choice lowers the frequency of tool changes, supporting uninterrupted production cycles and lower operating costs over time.

Improved chip control and machining reliability

The spiral‑fluted design with left‑hand spiral promotes controlled chip evacuation, particularly in through‑hole operations or interrupted feeds. Spiral flutes guide swarf away from the cutting zone, reducing the risk of re‑cutting and surface damage. Combined with the cylindrical shank and specified shank tolerance h6 from Ø 10 mm, the tool offers steady clamping and minimal runout, which further improves surface quality and dimensional stability during high‑precision finishing.

Practical benefits for workshop and production use

Form B configuration and the right combination of fluting and cutting material enable a straightforward integration into existing machining processes. The design emphasises operational efficiency — fewer passes, predictable final sizes and less downstream manual finishing. For operations that demand consistent hole geometry and low scrap rates, this reamer provides a pragmatic balance between precision, durability and operational ease.

FAQ

What materials can this reamer machine?
The TECWERK machine reamer is suitable for steel, GGG (ductile iron) and non‑ferrous metals, as specified in the product description.

What does H7 tolerance mean for finished holes?
H7 denotes a standard hole tolerance class; with the TECWERK reamer it results in consistent clearance for commonly paired shaft fits and repeatable assembly dimensions.

Is the shank compatible with standard tool holders?
The tool has a cylindrical shank with tolerance h6 from Ø 10 mm, which supports secure clamping in conventional holders that accept cylindrical shanks.

Why are spiral flutes with left‑hand helix used?
The spiral flutes with a left‑hand helix assist chip evacuation and help prevent chip recutting, contributing to improved surface finish and reduced clogging during reaming.

Does the tool use solid carbide or carbide inserts?
The specification indicates HM (carbide) cutting plates, providing wear resistance and stable cutting edges suitable for finishing operations.
