Carbide Step Drill Bit With Through Coolant Hole For Heavy Duty Machining

AMG's advanced carbide step drill with through-coolant technology delivers unmatched performance in heavy-duty machining. Designed for high-production environments, this innovative tool combines multiple drilling operations into one while maintaining exceptional tool life and hole quality.

Features

Integrated Step Design - Combines pilot hole and chamfering in single operation with precision-ground steps maintaining ±0.01mm diameter tolerance
Advanced Through-Coolant System - 2-4 coolant channels maintain 15-20Bar coolant pressure at cutting edge, reducing heat buildup by 40% in deep holes
Premium Carbide Construction - Sub-micron grain structure (0.5μm) for maximum edge retention with heavy-duty web design
Specialized Coating Options - AMG Hyper Coat (standard) for steel/stainless or diamond coating available for composites/CFRP

Performance Advantages

50% faster than conventional twist drills in stacked/stainless steel
No secondary deburring required (clean hole edges)
Consistent accuracy across all step diameters (±0.02mm)

Typical Applications

Automotive: Drilling+chamfering engine blocks
Aerospace: Stack material drilling
Energy: Flange hole preparation
General Engineering: High-volume production
