KSM drill indexable type

Description

1. Product Overview

The KSM Drill Indexable Type is a premium modular drilling system from Kennametal that combines the high feed rates and exceptional length-to-diameter (L/D) ratio capabilities of modular drills with the high speeds and low consumable costs of indexable drilling technology. Its primary industrial use is high-productivity hole-making in steel, cast iron, stainless steel, and exotics across diameters ranging from 28–70mm (1.102–2.756″) at 3–10×D depth ratios. The key value proposition is vastly improved productivity and capacity with reduced cost per hole, replacing both HSS and traditional indexable drilling solutions. This product is strategically important as it represents the current industry benchmark for large-diameter drilling applications, particularly critical in energy market sectors like windmill bearing ring production.

2. Key Specifications & Technical Characteristics

3. Core Industrial Applications

• Primary Industries:

  • Energy sector (windmill bearing rings, oil & gas components)

  • Automotive manufacturing (engine components, transmission parts)

  • Aerospace (exotic material drilling)

  • General metalworking and heavy machinery

• Specific Operational Use Cases:

  • Large-diameter drilling (28–70mm) at deep hole ratios (3–10×D)

  • Drilling through stacked materials and inclined exits

  • Cross-hole drilling up to 50% of drill diameter with accurate guidance

  • Interrupted cut conditions and difficult drilling environments

  • High-feed machining for maximum metal removal rates

• Performance Advantages:

  • Efficiency: High feed rates combined with high spindle speeds deliver increased metal removal rates

  • Durability: Reinforced cutting edges with superior wear resistance and edge chipping resistance extend tool life

  • Cost Advantage: Low consumable costs via replaceable inserts; reduced cost per hole compared to HSS and traditional indexable drills

  • Quality: Good surface finish and precise hole diameter accuracy from indexable inserts

4. Competitive Advantages

This product positions as a strategic sourcing decision for enterprises seeking to maximize drilling productivity while minimizing total cost per hole.
