Walter 21SST+ Drill Set with Box (01E621)

Description

Walter 01E621 #21 SST+ Drill Set with Box is a precision-engineered drill set designed for speed, accuracy, and durability. Made from premium cobalt HSS, these SST+ drill bits drill up to 30% faster than standard HSS bits, making them ideal for harder materials. Each bit features a 135° self-centering split-point to minimize walking and reduce thrust, while the bronze SST surface treatment enhances lubricity and extends tool life. The high-flow flute design allows rapid chip evacuation, and the round shank with back-tapered body ensures stability and control during use. Packaged in a shock-resistant, extra-thick polyethylene carrying case with clearly marked sizes, this set is perfect for professional workshops, industrial applications, and mobile use.
