Kanzawa K-302 Adjustable Spade Boring Bit, 22mm – 76mm Diameter

More economic than buying a full set of Forstner bits!

This adjustable hole boring bit, manufactured in Japan by Kanzawa, covers a wide range of diameters, taking away the need to have lots of cutters in your tool box.

Supplied with 2 steel cutting heads, large and small, to give a total capacity range from 22mm to 76mm diameter.

The cutting head is quickly set to the desired size using the metric graduations etched into it. Then locked into place using the tool provided.

• Small Blade 22-40mm diameter
• Large Blade 40-76mm diameter
• Cutting Depth Max 130mm
• Auger Shank Diameter 10mm
• Overall Length 160mm

The prominent centre point guides the bit, keeping it true and accurate.

The outer scribe cuts a clean splinter-free edge, the angled centre cutter then uses a shearing action to effectively remove the bulk of the material.

This type of bit is primarily intended for making through holes. Although it can be used for blind holes, the bottom of the hole will not be flat and may not be suitable for all applications.

Can be used in a drill press or with a portable electric drill (not recommended for use in a woodturning lathe).

For drilling blind holes or for using on a woodturning lathe see products K-303 or K-304.
