Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.81mm

The Toolex Reamer — Straight Shank, Spiral Flute, Stub Length, 12.81 mm diameter — is a precision carbide finishing tool designed to bring drilled holes to an exact size with repeatable accuracy. Built for compact toolholders and tight bore work, it’s ideal for engineers, fabricators, and hobbyists who require reliable, consistent hole dimensions in a range of materials. DIN 8093 compatibility and ISO H4 tolerance help ensure interchangeability with standard setups and predictable results.

Engineered as an intermediate precision carbide (k10) stub reamer, this tool combines durable edge retention with a compact profile that suits finishing passes without excessive tool deflection. Its left-hand spiral flute works with right-hand cutting machinery to deliver smooth finishes, while the through-coolant design directs coolant directly to the cutting edge for effective cooling and chip evacuation. The combination supports stable hole sizing even in challenging materials.

• K10 carbide (intermediate precision) construction: Delivers wear resistance and repeatable hole sizing for dependable long-term performance.
• Left-hand spiral flute with right-hand cutting: Aims for stable finishing and efficient chip control on standard machine tools.
• Through coolant with DIN 8093 / ISO H4 tolerance: Through-coolant design improves cooling and chip removal; tight H4 tolerance and DIN 8093 compatibility support precise, repeatable results.

Manufactured to order, this reamer typically ships within 24–48 hours, allowing you to plan production around your needs without long lead times. Its carbide construction and precise tolerances help reduce rework, improve part quality, and keep your workflow moving efficiently.
