Down Cut 2 Flute Spiral with Chipbreakers
Product Description
Chipbreakers break up chips into smaller debris which eject faster.
Chipbreakers can thus benefit the cutting operation by:
• increasing feedrates and therefore bigger chipload
• lowering cutting temperature
• improve chip ejection
The actual chipbreakers/serrations along the flutes are arranged in a staggered format, ensuring that one flute cuts with a breaker and one flute cuts with a finishing cut.
Chipbreakers versus Roughing Spirals (Hogger bits)
• main difference is tool geometry relating to the chipbreaker arrangement
• breakers are staggered on a 'chipbreaker' and each breaker is always complemented with a finishing flute
• roughing spirals have continuous breakers with no finishing flute to smooth the edge, literally shred the chip
• roughing spirals produce the smallest chip but at a loss of surface finish
• higher feedrates can be achieved with roughing spirals
CNC common practice:
• chipload is reduced by 25% when DOC exceeds 2 × CED
• chipload is reduced by 50% when DOC exceeds 3 × CED
Chipbreakers can reduce the 25% and 50% chipload loss because of better chip ejection; so faster feeds at greater DOC.
Recommended for thicker stock and CNC nesting, including hardwoods, softwoods, plywood, MDF, engineered boards and solid surface cut-outs where finish is of lesser concern.
