High-efficiency drilling head KSEM PLUS™

high-performanceprecisionhigh-speed

Product Overview
The KSEM PLUS modular drill covers drilling applications in a diameter range from 28 mm to 101.6 mm (1.102–4″) up to 10×D. KSEM PLUS combines the advantages of a modular drill and an indexable drill, providing high speed and feed capability with large length-to-diameter ratio at low consumable cost. This modular system enables quick tool set-up and reduces tool inventory needs.

Head Styles

• The KSEM PLUS A1 head for lowest cost per hole.
• The KSEM PLUS B1 head for challenging conditions like stacked plates, cross holes, and inclined exits.
• Interchangeable head styles with two fully effective cutting edges deliver excellent productivity in many materials and cutting conditions.

NEW! KSEM PLUS HPP Inserts
Eliminate the need for pilot holes in deep-hole drilling. The HPP inserts feature a raised center point that acts as a guide pin to maintain straightness and precision, suited to high-volume production such as wind-energy component drilling.

• HP cutting geometry for maximum metal removal rates
• Raised center point for straightness and precision
• Corner chamfer protects main cutting edge for extended tool life

KCMS40 for KSEM PLUS MD Inserts
Produced with advanced HiPIMS coating technology, KCMS40 is formulated for machining stainless steel, high-temperature alloys and long-chipping steels.

• Maximum process reliability with long tool life on stainless materials
• Smooth coating surface prevents build-up on cutting edges for consistent machining
• Grade combines optimum coating adhesion and high carbide toughness
• MD geometry provides superior chip control and surface finish

Applications

• Large-diameter drilling (28 mm to 101.6 mm)
• Deep-hole drilling up to 10×D
• Challenging conditions: stacked plates, cross holes, inclined exits
• High-volume drilling typical in wind-energy component manufacture
