Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 7.83mm

The Toolex Reamer is a carbide stub-length, straight-shank finishing tool sized at 7.83 mm, designed for through-hole work where precise bore size matters. Crafted from intermediate precision carbide (k10), it combines a left-hand spiral flute with right-hand cutting, through coolant, and adheres to DIN 8093 with a D = ISO H4 tolerance for dependable, repeatable results.

Supplied by Toolex Ltd, this reamer is manufactured to order with an estimated despatch window of 24–48 hours. When a listing notes “in stock,” that refers to blanks available for machining into the finished reamer, not a ready-to-ship completed tool.

• Through-Coolant design for cleaner bores: Allows coolant to reach the cutting edges and flush chips, helping maintain dimensional accuracy and surface finish while reducing heat buildup.
• Carbide stub-length with straight shank: Delivers greater rigidity and stability in demanding setups, helping achieve consistent hole sizes and smoother finishes with minimal deflection.
• DIN 8093 / ISO H4 tolerance for 7.83 mm: Provides reliable, repeatable bore sizing across production runs, reducing rework and ensuring fitment consistency in assemblies.

Using this reamer translates to tighter, more consistent holes, faster setup, and fewer rework cycles. Its durable carbide construction and coolant-assisted design help you achieve reliable results in a wide range of through-hole applications, making it a dependable choice for engineers, machinists, and production teams seeking precise, repeatable bore finishes.
