Members Ferryman Posted February 23, 2020 Members Report Posted February 23, 2020 I have had this cutter for a good few years and I think it was intended to either cut rubber or leather washers. The blade is made from a length of 1/4" steel rod with one end reduced down and profiled to form the blade. Today the blade snapped so I ground it down and sharpened it to finish the job, but I wonder was this a commercially available item or home made. The central point is spring loaded. Quote
Contributing Member fredk Posted February 23, 2020 Contributing Member Report Posted February 23, 2020 yes, versions are commonly available. some with two cutting blades. its a hole or disc cutter, for metal or wood. eg; https://www.ebay.co.uk/itm/ADJUSTABLE-CIRCLE-HOLE-CUTTING-DRILL-SAW-CHROME-/183252805928?hash=item2aaab7e928 Quote
Members Ferryman Posted February 23, 2020 Author Members Report Posted February 23, 2020 Hi fredk Yes I know what it is for, I was hoping somebody would say oh that was made by xxxxxxx company and then I could order a new blade assembly, but it looks like I will have to make one. Quote

Northmount Posted February 24, 2020 Report Posted February 24, 2020 Don't try using in a powered portable drill! Can wrap things up in a hurry! For powered use, use it in a drill press, and what ever material you are cutting should be clamped down securely. Tom Quote
MikeRock Posted February 24, 2020 Report Posted February 24, 2020 Tom, you are sure right on that. I used a milling machine on 'really slow', and used brace and bit setup for many things. Made water pump cylinder leathers, hydraulic cylinder seals, odd jobs. A friend of mine used to be a hand gasket maker at Chicago Rawhide, I got it from him. Also got a 38 Chevy pickup from him :)))) God bless and stay safe when using power tools. THINK before you press that little button! Quote
