Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 15.87mm

The Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 is a precision carbide finishing tool designed to bring holes to a 15.87 mm diameter with ISO H4 tolerance. Its straight shank and stub-length form suit tight toolholders and confined work envelopes, while the left-hand spiral flute paired with right-hand cutting delivers stable, predictable reaming for through-hole applications.

Manufactured to order by Toolex Ltd, dispatch is typically 24–48 hours. The reamer conforms to DIN 8093, using intermediate precision carbide (k10) to balance durability with accuracy and provide consistent hole sizes. Tolerance is D = ISO H4.

• Through coolant; chip evacuation and edge cooling: Directs coolant through the flute to flush chips and keep the cutting edge cool, helping maintain accuracy and extend tool life.
• Carbide with ISO H4 tolerance: Intermediate precision carbide (k10) delivers repeatable hole sizes at D = ISO H4 for reliable finishing results.
• Rigid stub-length straight shank with left-hand flute: The compact, stiff form reduces deflection in tight spaces, while the left-hand spiral flute and right-hand cutting promote stable cutting and a smooth surface finish.

This reamer helps you finish holes accurately and consistently, reducing rework and improving workflow in through-hole machining. The combination of through coolant, rigid stub-length design, and DIN 8093-compliant tolerances supports dependable performance across repeated jobs, giving you confident, repeatable results.
