Marlco Litecut Keyway Push Broaches
Manufactured to BS4235;Part 1:1972 (normal fit Js9) and DIN6885 for Metric sizes, and BS46;Part 1:1958(1985) for Inch sizes. Precision made from high speed steel and simple to use with minimal set-up. The cutting geometry will suit most materials. Push broaches are designed for use in hand-operated or hydraulic mandrel presses, depending on load. Load per tooth, given in the tables, is based on a UTS of 400N/mm2 (approx. 25 tons/sq in). For other materials, adjust accordingly. It is important that broaches are reground when blunt and before damage occurs to the teeth. The use of cutting fluid is essential, and for steel, an oil with high pressure additives is recommended. Keyways from 2mm to 25mm width and bore diameters of 6mm to 95mm are possible. Both parallel and taper keyways can be cut by using the appropriate guide. Broach style L2 and L2M require the use of an extension shank which should be ordered separately. The shims specified for standard depth keyways can be adjusted to suit particular applications. Parallel broaches are listed and supplied as standard. Broaches for taper keyways are available to order.
For all dimensional and technical specifications please refer to our catalogue.
