New interchangeable drill bits from WIDIA.

4 edged indexble drill capable of drilling up to 5xD.

Flexible and Versatile

Top Cut 4 indexable drills are equipped with centering capabilities and inboard and outboard inserts delivering outstanding flexibility and versatility in multiple materials. This indexable drill portfolio encompasses dual four-edged front inserts, instead of a traditional drill point geometry, enabling it to perform in a variety of applications on multiple materials. This drill is capable of supporting a variety of applications including through and cross-hole, inclined entry and exit, 45-degree corner, half cylindrical, concave, blind, and chain drilling.

NEW! WM35PH grade for V36 and V38 geometries.

• Ensures high process reliability and reputability in stainless steels and high-temp alloys
• Hi-PIMS coating prevents high depth-of-cut notching chipping and edge build-up

Features and Benefits

• Standard diameter range covering 12-68mm
• 4 real cutting edges per insert
• 5 grades to achieve higher tool life at accelerated speeds: WM35PH, WU25CH, WU40PH, WPK10CH, WN10PH
• X-offset design to adjust diameter size on turning machines and optimize tolerances on machining centers
• Coolant channels exit right behind the cutting edge
• Differentiated insert shapes to avoid grade mixing between central and periphery inserts
• Optimized flutes to contain chips during machining 
• Flanged shank to increase the overall drill stability in deep-drilling applications
