The variable 4-6 teeth per inch design with a positive 10° tooth angle provides a range of benefits including a faster, more aggressive cut and improved heat dispersion. Made from Matrix II steel, they retain their original tooth hardness even in high working temperatures. The high quality manufacturing techniques used in this hole saw kit ensure high rotational precision, making them suitable for use with both in-hand and pillar drills (manual feed only). Supplied in a plastic case, the Hole Saw range is ideal for cutting all types of materials, including:  Steel up to 1000 N/mm² strength Stainless steel and acid resistant steel Non-ferrous metals Cast iron Aluminium Wood Medium density fibreboard (MDF) Gypsum plasterboard Sandwich materials PVC CONTENTS 6x Hole Saws: 25mm 32mm 40mm 54mm 68mm 76mm 1x Arbor For ø 14-30 mm (49567010) 1x Arbor For ø 32-152 mm (49569100) 2x Pilot Drill Bits 1x ⅛″ Allen Key FEATURES Improved heat dispersion during cutting ensures that the teeth stay sharper for longer Deeper curved gullets provide more efficient chip clearance preventing clogging and heat build up Special shaped tooth angle has less tendency to snag on thinner materials Teeth are altenate side set to minimise binding and friction Matrix II steel contains 8% cobalt allowing the teeth to retain the original tooth hardness even at high working temperatures when used in metal cutting applications Bi-Metal construction 1.27 mm thick steel holesaw body is rigid to retain its shape but also has built in elasticity Effective sawing depth is 41 mm The back plates are constructed with thick steel thus the holes will not enlarge over time Thick backs add strength and rigidity minimising vibrations 4 drive pin holes for easier arbor location Diagonal slots aid the removal and ejection of the core SPECIFICATION Pack Qty: 10 Pcs Article No.: 49224201
