MULTI-SHARP DRILL SHARPENER
What do you typically do when your drill bits become blunt? Most of us tend to throw them away, because they no longer serve the purpose for which they were designed. A dull drill bit is not only frustrating to use, it can also be dangerous. But what if you could extend the life of your bits, by sharpening them yourself?
The Multi-Sharp Drill Sharpener lets you do just that, whether it’s a bit made for drilling through steel, wood, or masonry, or even if it’s a spade bit. The device clamps your bits in such a way that the grinding stones accurately correct the tip angle, and restore the cutting edges. Use it on all of your bits, from 3 mm in diameter right up to 13 mm; it can even handle centre-point wood bits.
The sharpener’s jigs are set up with all of the required tip-angle geometry, positioning the bit above the grinding wheels. The unique cam action ensures the right rake and chisel edge is achieved.
The carbide sharpening wheels are made from aluminium oxide and silicon, and are durable enough to restore up to 150 high-speed steel bits (for wood) and 75 slotted driveshaft masonry bits.
It’s conveniently designed to fit any power drill, which will drive the grading wheels, and replacement wheels are available when yours eventually wear out. Simply follow the instructions – which advise the correct speed to use for various bits – to make your blunt bits as good as new.
