Dormer Pramet C80 25.0mm x 14mm HSS-E Screwed Shank T Slot Cutter DIN 851 is a precision T-slot milling tool designed for reliable, repeatable slotting in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys. Sized for DIN 851 setups, it combines a robust 25 mm cutting diameter with a secure combi shank for dependable clamping in demanding CNC applications.

• Diameter: 25 mm cutting diameter for efficient T-slot milling with predictable chip removal.
• Teeth: 8-tooth configuration provides a balance between material removal and surface finish.
• Depth of cut: 11 mm maximum DOC for productive slotting within a single pass.
• Overall length: 82 mm to suit standard machining configurations and reach.
• DIN standard: Compliant with DIN 851 for consistent compatibility with machine tool setups.
• Shank type: 16 mm combi shank with Weldon flat and thread for secure, repeatable clamping.
• Material and finish: Cobalt-based HSS-E with bright finish for enhanced wear resistance and longevity.
• Geometry: 15° helix and 10° rake angle optimized for T-slot milling in a range of metals.
• Applications: Ideal for creating and finishing T-slots in steel, stainless steel, cast iron, and other alloys.

This cutter is engineered to deliver consistent performance across traditional and demanding workholding scenarios. The cobalt-enhanced HSS-E substrate provides superior hot hardness, helping maintain cutting force and edge wear under high-temperature conditions. The 15° helix supports smooth chip flow, while the 10° rake angle aids in reducing built-up edge and improving finish. The screwed 16 mm combi shank with Weldon flat ensures a secure grip and straight alignment, promoting repeatable results in CNC machines that require DIN 851 compatibility. Designed for durability and precision, it supports reliable T-slot milling in a variety of common workshop metals, making it a dependable choice for fixture plates, machine beds, and dedicated T-slot channels.
