Gray cast iron’s abrasive nature traditionally demands frequent tool changes. The M4 Drill and Tap Set in 6542 HSS redefines this narrative, offering extended tool life and precision for engine blocks and hydraulic manifolds.
Engineering Innovations
Reinforced Web Thickness: 40% thicker than standard bits to combat cast iron’s abrasiveness.
Chip Splitter Design: Breaks long cast iron chips into manageable segments.
Steam Oxide Coating: Reduces built-up edge (BUE) on cutting surfaces.
Performance Data
1,200 Holes in Class 40 Cast Iron: Before regrinding.
Tap Speed: 25 SFM (7.6 m/min) with flood coolant.
Hole Tolerance: H8 for press-fit dowel pins.
Agricultural Machinery Application
Tapping M4 mounting threads in tractor transmission housings:
90-Second Cycle Time: Down from 3 minutes.
Consistent 6H Thread Quality: Across 500°C thermal cycling tests.
30% Coolant Reduction: Via efficient chip evacuation.
Technical Details
Length of Drill: 8.5mm (M4)
Length of flute: 13.5mm
Shank: CAT40 compatible for machining centers
A must-have for automotive foundries and heavy equipment repair shops.
