Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 9.37mm

The Toolex Reamer is a straight-shank carbide stub reamer designed for through-coolant bore finishing. At 9.37 mm in diameter, it combines a left-hand spiral flute with right-hand cutting to deliver precise hole size and a clean exit across a range of metals.

Made by Toolex Ltd. as an intermediate precision tool (k10 carbide) and DIN 8093 compliant, it carries ISO H4 tolerance. Because it is manufactured to order, despatch typically occurs within 24–48 hours. The through-coolant design channels coolant directly to the cutting edge for effective heat management and chip evacuation, while the stub-length geometry provides rigidity in shallow bores for stable cutting.

• Left-hand spiral flute with right-hand cutting: Encourages stable bore progression and efficient chip control for consistent hole size and finishing.
• Through coolant and straight shank: Delivers direct cooling and chip evacuation at the cutting edge, while the straight shank simplifies clamping in standard tooling setups.
• ISO H4 tolerance with intermediate carbide (k10): Ensures precise bore size and wear-resistant performance for reliable results across common engineering materials.

This reamer helps you achieve precise 9.37 mm holes with a smooth bore finish, minimizing finishing passes and rework. The through-coolant design keeps heat in check and extends tool life, while the stub-length geometry and carbide construction support rigid, repeatable results in shallow bores. Manufactured to order by Toolex, it adheres to DIN 8093 and ISO H4 standards for dependable performance in demanding workshops.
