This slot drill is built to deliver clean slots and controlled milling action across a range of metals. The combination of a 30° helix and 12° rake optimizes cutting efficiency and reduces chatter during deep or wide slots. The powder-metallurgical HSS‑E construction provides improved wear resistance and tool life compared with standard HSS options, helping you maintain dimensional accuracy and finish. The flatted Weldon shank and generous reach allow secure clamping and access to pockets and shoulders without frequent tool changes, making it a dependable choice for routine manufacturing and repair work.
