• Length of cut: 16 mm
• Overall length: 66 mm
• Shank: Weldon 10 mm with a flatted surface for secure clamping
• Material: HSS-E, powder-metallurgical with bright finish for enhanced wear resistance
• Helix angle: 30° to optimize chip formation and evacuation
• Rake angle: 12° to improve cutting action on shoulders and during ramping
• Standard: DIN 844 K, short series slot drill
• Applications: slot milling, shoulder milling, and ramping in steel, cast steel, and copper alloys

This tool is engineered for durability and consistency in production and repair environments. The powder-metallurgy HSS-E core combines toughness with wear resistance, helping extend tool life when cutting harder materials. The bright finish reduces friction and helps resist built-up edge, while the 30° helix and 12° rake angle promote smooth entry, clean slots, and steady performance across a range of milling tasks. The flatted Weldon shank ensures repeatable seating in collets and holders, supporting precise, vibration-free cutting.
