GWS 1/4 in Carbide Twist Drill AlTiN Coated Jobber Drill Bit

This is a new GWS Tool Group solid carbide jobber-length twist drill in 1/4 in (0.2500 in) diameter, catalog number 460-102600B, with an AlTiN (Aluminum Titanium Nitride) coating as indicated on the label. AlTiN coating provides a hardness of approximately 3,000 HV and a maximum working temperature tolerance of around 1,600 °F (871 °C), making it well-suited for dry or near-dry machining of hardened steels, cast iron, stainless steel, and high-temperature alloys. Solid carbide construction delivers significantly higher rigidity and wear resistance compared to HSS or cobalt alternatives, enabling higher cutting speeds and longer tool life in CNC machining centers and rigid drill press setups. The drill features a standard 118° or 135° split-point geometry typical of carbide jobber drills, a straight shank compatible with standard 1/4 in chucks and collets, and two-flute helical construction for efficient chip evacuation.
