Engineered to deliver consistent, clean slots with controlled chip evacuation, this tool’s extra-short series and neck relief minimize rubbing and deflection in confined spaces. The powder metallurgical HSS-E substrate offers improved hardness and wear resistance, helping extend tool life when cutting softer metals like free-machining steels and copper alloys. The 30° helix and 12° rake optimize cutting geometry for accurate shoulders and straight, true slots, while the Weldon shank ensures secure, repeatable clamping in compatible holders.
