Drill's Steep Gash Angle Facilitates Better Hole Quality
Walter USA says that a steep gash angle from its new DC 160 Advance solid carbide drill provides ample space for secure chip flow, which results in improved hole quality and reduced feed force.
Walter USA says that its new DC160 Advance solid carbide drill delivers high productivity in a wide variety of materials and can be used in a broad range of applications. The margins are located in an advanced, forward position to ensure rapid guidance in the hole. Walter says that a steep gash angle provides ample space for secure chip flow, which results in improved hole quality and reduced feed force. According to the company, a new, thinner web provides for better positioning accuracy and improved roundness. The DC160 Advance is available in 3, 5 and 8×D and features grade WJ30ET, which includes a Walter coating to optimize tool life. It has a cylindrical shank ground to an h6 tolerance, which makes it suitable for shrink-fit and hydraulic holders. The point angle is 140 degrees, and Walter recommends a coolant pressure of 145–580 psi (10–40 bar). With internal coolant, the drill is suitable for ISO P, M, K, N, S, H and O material types.
