Top Cut 4™ Indexable Drills • Top Cut 4 • 2x four true cutting edges.  • Cutting edge profile of central and periphery insert work together, leading to high stabilisation of the drill, preventing drifting of the tool even on irregular surfaces.  • X-offset design to adjust diameter size on turning machines and optimise tolerances on machining centres.  • Apply where speed and economy are prime considerations.  • Four grades to achieve higher tool life at accelerated speeds: — WU25CH grade for highest metal removal rate in general applications. — WU40PH grade for high toughness demands. Chip Flute Exit — WPK10CH grade for high-speed applications. Steeper chip flute exit to — WN10PH grade specific for aluminium and other non-ferrous materials.  reduce the overall length and increase rigidity. Coolant Channels Enhanced coolant holes to get more lubrication at the cutting edge. SL Shank Style Metric portfolio: shank sizes are 20mm, 25mm, 32mm, and 40mm, based on the cutting diameter for all the L/D ratios. Insert Positioning Optimised insert positioning Gash to achieve the maximum drill Improved gash design on both insert stability, hole tolerance, and pocket seats for a better chip evacuation. surface quality, above all in deep-drilling applications.
