Chipbreaker Profile

The SGS54628 features an advanced flute profile optimized for cast iron machining. The 3-flute 3×D design provides superior chip evacuation compared to standard 2-flute drills, reducing the risk of chip packing and hole distortion in medium-depth applications. The polished flute surface minimizes built-up edge (BUE) and ensures smooth chip flow even at elevated feed rates. The specialized land width and margin design enhance drill stability and hole straightness, particularly in deep-hole applications up to 3×D.

Chipbreaker StyleContinuous helical flute with optimized gash
Max Drilling Depth3×D (standard), 5×D (with peck cycle)

Operating Guidelines

  • Coolant: High-pressure internal coolant (minimum 70 bar) is strongly recommended for optimal chip evacuation and tool life.
  • Run-in: Reduce feed by 20% for the first 5 holes to allow the cutting edge to stabilize.
  • Pecking: For holes deeper than 2×D, use a peck depth of 1×D with full retract to clear chips.
  • Toolholder: Use hydraulic or shrink-fit holders with TIR ≤ 0.003 mm for best results.
  • Spindle Warm-up: Allow 10-15 minutes of spindle warm-up before precision drilling operations.
  • Inspection: Check drill point under microscope after every 50 holes for wear land development.
