Push broaches (keyway broaches)

• For manufacturing true-to-size and precisely centred keyways in accordance with DIN 6885
• Can be used on normal workshop presses (hand press or hydraulic press); no special machinery required
• Low tooling time
• Good surface finish on machined workpieces
• Manufacturing time for one keyway only approx. 1 minute
• Broaches supplied with inserts for achieving the cutting depth
• Special alloy HSS steel for machining any materials with a hardness of up to 34 HRC
• Broaches with other rake angles are available on request for machining solid or very soft materials.
• Square and multi-purpose four square broaches are available on request.
• From size 32 x 102, guide bush without collar
• Use:
  1. Slide guide bush into workpiece bore and insert broach until the first tooth on the workpiece is standing upright
  2. Lubricate broach
  3. Push broach in approx. 1/3
  4. Briefly release plunger and push broach in fully
