Flow Designs Metric Step Drill Bit: HSS Titanium Coated 3mm - 13mm

This is a metric step drill bit from Flow Designs with a titanium coated HSS body that steps through 11 sizes from 3mm to 13mm. It has a 1/4 inch (6.35mm) hex shank and is intended for cutting wood or thin metal plate and hollow section, leaving a clean chamfered hole, and it can also be used on bar, tube and box section. Flow Designs says it is best suited to mild steel and softer alloys and is not the best choice for 316 stainless steel. The listing recommends a clean, dry, centre punched surface, plenty of cutting fluid or drill lubricant and a slow speed to keep the bit cool and extend its life.
