Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 20.12mm

Engineered for precise through-hole sizing, the Toolex Reamer with a straight shank and stub-length design delivers reliable, repeatable results at a 20.12 mm diameter. This intermediate precision carbide reamer (k10) features a left-hand spiral flute with right-hand cutting and through coolant, conforming to DIN 8093 and delivering a D = ISO H4 tolerance. Supplied by Toolex Ltd, it is manufactured to order, with despatch typically within 24–48 hours. The stub-length form provides rigidity in tight or interrupted work, helping you achieve a clean, accurate bore every time.

• Flute geometry: left-hand spiral flute, right-hand cutting: Optimizes cutting stability and chip control for consistent hole size and finish.
• Through coolant: Through-coolant delivery enhances cooling and chip evacuation, reducing heat buildup and improving tool life.
• Carbide (k10) with ISO H4 tolerance (DIN 8093): Durable cutting edges plus tight, repeatable hole dimensions for reliable production results.

This reamer is designed for engineers, shop floor technicians, and hobbyists who demand accuracy and reliability in through-hole reaming tasks. The combination of carbide hardness, precise tolerance, and efficient coolant delivery helps shorten cycles, reduces rework, and improves overall part quality in metalworking, tooling, and fabrication applications.
