Walter (Waukesha, WI) has introduced the D4140 replaceable tip drill, a tough and versatile new drill that delivers maximum process reliability and extended tool life. The D4140 advantage stems from its design and construction, featuring a hardened and polished surface that offers exceptional resistance to friction wear. The drill’s ground and polished flutes, similar to those of solid-carbide drills, ensure smooth and secure chip evacuation. The drill features:
- Precision coolant delivery directly to the cutting edge, avoiding thermal shocks to the edge and resulting in longer tool life and maximum process reliability.
- 100° prismatic insert seating for the P600x Xtra·tec Point inserts, providing secure clamping to ensure precise, high-quality holes.
Drills are available in 3 x D, 5 x D and 7 x D and in 0.47 in. to 1.26 in. (12-31.99 mm) dia. The drills have universal applications in a variety of materials and users can also benefit from simple indexable insert selection through Walter Color Select.
