Tapered Drill Bit Set - Onishi

Tapered drill bit makes perfect matching pre drilling hole for screws and nails which means fasteners will get more holding strength. 

A set of 3 bits - 3mm, 4mm and 5mm

HSS steel

For wood only, use with under 3000RPM

Made in Japan

Great product but must handle with care. Quite easy to snap. I have snapped few of them by not keeping drill straight when drilling and tipping over a drill. It has Japanese standard hex shank. Does not lock into Australian standard impact drivers.
