Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 16.95mm

The Toolex Straight Shank Reamer with a spiral flute and stub length is a carbide reaming tool designed for through-coolant applications. With a 16.95 mm diameter, a left-hand spiral flute and right-hand cutting, it follows DIN 8093 and ISO H4 tolerance for reliable hole finishing. Made from intermediate-precision carbide (k10), this tool is built to deliver consistent results in a range of machining materials.

Manufactured to order by Toolex Ltd., this reamer is not a stock item—please allow 24–48 hours for despatch. The listing notes that the stock label refers to blanks ready to be machined into the final reamer. The through-coolant design helps channel coolant directly to the cut, aiding chip removal and heat control for cleaner, more accurate holes.

• Through-Coolant delivery: Direct coolant through the tool to the cutting edges improves chip removal and thermal control, helping achieve cleaner holes and longer tool life in demanding reaming tasks.
• Carbide (K10) stub length for rigidity: Stub-length carbide construction provides stiffness in deep bores, delivering stable hole size and a smoother finish with reduced deflection.
• DIN 8093 / ISO H4 precision: Tight H4 tolerance ensures repeatable results and better interchangeability across parts and assemblies.

Used in production environments or by serious hobbyists, this reamer helps streamline workflows by delivering consistent bore quality on the first pass. Its straight shank fits standard toolholders, and the left-hand flute with right-hand cut is optimized for predictable cutting performance, making it a dependable choice for precise hole finishing.
