Spiral four-flute step bits made from upgraded HSS 4341 with a titanium coating and 1/4" hex shank. Three-bit set covers 4–12mm, 4–20mm and 4–32mm and is suitable for use with impact drivers, drill presses and power drills.
Cleaner, faster drilling - with spiral four-flute design
Four flutes channel metal swarf away from the cutting edge, reducing clogging and spray of chips during drilling. The spiral profile maintains cut engagement while keeping holes clear.
Fewer stoppages for chip clearing and consistently neater hole edges, so work progresses faster with less mess.
Secure grip under torque - thanks to 1/4" hex shank and 118° X-type openings
A 1/4" (6.35mm) hex shank prevents slipping in chucks and drivers, while 118° X-type openings create a sharper entry for quicker starts. Together they improve torque transfer and centring.
More reliable starts and reduced cam-out when using impact drivers or hand drills, making hole placement simpler on thin materials.
Longer wear life - thanks to titanium coating and HSS 4341 construction
Manufactured from upgraded HSS 4341 and finished with a titanium coating to boost wear resistance and guard against corrosion. The combination preserves cutting edges under regular use.
Bits retain sharpness for longer and stand up to workshop use, reducing the frequency of replacements.
