The Unique J-Cut combination structure
features a straight cutting edge at the small end and a spiral cutting edge at
the large end (patent pending), integrating the strengths of both while
addressing their weaknesses. Key highlights include:
Straight Cutting Edge (Small End): Provides strength and sharpness
with an enlarged groove for improved chip removal and heat dissipation,
enhancing cutting efficiency and extending tool life. It also offers better
centering and reduced slippage when processing smaller holes.
Spiral Cutting Edge (Large End): Significantly reduces axial and
radial cutting resistance, enabling smooth, steady cutting with light feeds. It
efficiently removes larger allowances while achieving a smooth chamfered
surface.
Effective Heat Management: The spiral groove quickly dissipates
cutting heat, creating a larger chip removal space and promoting cooling for
both the cutting edge and the workpiece.
