Hole Saw Accessories

There are two sizes of holesaw arbor and they work with specific sizes; number 1 arbors fit holesaws ranging from 14mm – 30mm and number 2 arbors fit holesaws ranging from 32mm – 210mm, this is a standard which has been adopted by all holesaw manufacturers. The replaceable pilot drill mounted within the arbor is used to make the first hole in the material and this is used to centre the holesaw, therefore, the pilot drill must be capable of drilling the same material the holesaw is to be used on. Many pilot drills are made from standard high speed steel which become dull very quickly when used in materials such as stainless steel; Maxitek pilot drills are manufactured using M42 cobalt which improves cutting speed and dramatically increases the life of the pilot drill, let’s not forget, when the holesaw is changed the pilot drill remains in the arbor, if anything, the pilot drill needs to be able to outlast the holesaw. Extension bars can be a useful accessory if access and reach is a problem. Protrade stock a range of holesaw accessories such as holesaw pilot drills, holesaw arbors and extension bars from manufacturers such as Maxitek and Lenox.
