Replaceable Tip Drill

Aug. 20, 2018
Walter's replaceable tip drill features precision coolant delivery.

The D4140, a tough and versatile drill that delivers maximum process reliability and extended tool life, offers exceptional friction wear resistance, efficient chip evacuation, thermal shock resistance and superior hole quality.

 

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, like those of solid-carbide drills, ensure smooth and secure chip evacuation.

 

The drill’s design 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. Additionally, the drill’s 100-deg. prismatic insert seating for the P600x Xtra·tec Point inserts provide secure clamping ensuring 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.
