Maschinenreibahle DIN 8093 H7 Form B D.12mm HM TECWERK — machine reamer with carbide cutting inserts and H7 tolerance

Maschinenreibahle DIN 8093 H7 Form B D.12mm HM TECWERK offers standard‑compliant reaming for metalworking applications, designed as a cylinder‑shank tool for accurate hole finishing in steel and non‑ferrous materials

• DIN 8093 H7 tolerance
• Carbide (HM) cutting inserts
• Cylindrical shank, shaft tolerance h6
• Left‑hand helical flutes, right‑cutting

High‑accuracy finishing that meets machining standards

The reamer is engineered to deliver repeatable H7 tolerance in line with DIN 8093, ensuring holes meet tight dimensional requirements without extensive hand‑finishing. Using a tool with defined tolerance bands reduces scrap rates and shortens inspection times, since measured diameters reliably fall within specification. The presence of carbide cutting inserts supports sustained cutting performance and maintains bore geometry over longer production runs, which translates into fewer tool changes and higher uptime.

Designed cutting geometry for effective chip control

Helical flute geometry with a left‑hand helix combined with a right‑cutting action improves chip evacuation and minimises chatter during reaming operations. Better chip flow reduces the risk of built‑up edge and surface scoring, producing a superior surface finish that often removes the need for secondary polishing. The tool’s cutting concept is therefore particularly beneficial in mixed‑material batches where consistent surface quality is required, such as components that include both steel and non‑ferrous metals.

Robust shank and machine compatibility for stable operation

A cylindrical shank with a shaft tolerance of h6 from Ø 10 mm supports secure clamping and low runout when mounted in standard toolholders, which helps preserve bore accuracy and prolong cutting insert life. The tool’s Form B configuration is compatible with common machine setups, permitting straightforward integration into existing production lines. Reduced runout and vibration lead to fewer rejected parts and a steadier process capability index for precision workshops.

Material versatility and intended applications

Specified for use with steel, GGG (ductile cast iron) and non‑ferrous alloys, the reamer suits a broad range of workshop tasks where final hole diameter and surface integrity are critical. The combination of HM (carbide) inserts and helical fluting addresses both strength and thermal resistance, allowing reliable performance when finishing holes from Ø 10.0 mm upwards. This versatility supports consolidated tooling strategies, enabling fewer tool changeovers across diverse jobs.

Practical advantages in daily production

Incorporating a DIN‑standard reamer with replaceable carbide inserts reduces total tooling cost over time by separating the cutting edge from the body; only the inserts require replacement when worn. Consistent hole tolerances mean shorter downstream assembly checks and less rework. For procurement and toolroom managers, this translates into measurable productivity gains and simpler inventory management when paired with Metav Werkzeuge’s supply chain services.

FAQ

What material range is this reamer suitable for?
The answer: The Maschinenreibahle DIN 8093 H7 Form B D.12mm HM TECWERK is specified for steel, GGG (ductile cast iron) and various non‑ferrous metals from Ø 10.0 mm upwards.

How does the H7 tolerance affect final bore quality?
The answer: A tool produced to H7 tolerance yields consistent hole diameters within standard tolerance limits, so the TECWERK reamer reduces the need for manual finishing and supports reliable assembly fits.

What is the significance of the shaft tolerance h6?
The answer: A shaft tolerance h6 from Ø 10 mm ensures precise clamping and low runout in standard holders, improving bore accuracy and extending cutting insert life for the TECWERK machine reamer (SKU 2000865753NW).

Are the cutting edges replaceable?
The answer: Yes; the reamer uses HM (carbide) cutting inserts, allowing the cutting parts to be replaced without discarding the whole tool body, which lowers long‑term tooling costs.

Which machines are compatible with Form B cylinder shanks?
The answer: Form B cylinder shanks are compatible with conventional toolholders and collet chucks used in CNC and conventional machines, enabling straightforward integration of the TECWERK reamer into existing setups.
