An excellent improvement to our standard hollow live centre, this Evolution Series centre features three chip ejection ports so that during use the bit doesn't have to be completely withdrawn from the tailstock. With short and long removable points, twin ball bearings and an 8mm(5/16") diameter through hole, this centre is an invaluable aid when long hole boring. The short point protrudes a mere 3mm beyond the ring and allows an accurate impression of the ring to be made on the end of the timber. Having made the impression, the point can be removed from the centre and the work relocated on the ring impression, allowing an accurate hole to be bored. When boring right through, the timber is drilled from one end then reversed, a counterbore drive is used to hold the timber in the headstock and the boring process repeated from the tailstock end. Fitting the long point gives good access for all sorts of miniature work, including light pulls and lace bobbins. A truly multi-functional accessory, worthy of a place in any turner's tool kit.
