Walter-titex 5057133 Screw Machine Drill Bit 0.1719 in

Product Description

The WALTER-TITEX 5057133 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit delivers the hardness and heat resistance needed for productive cutting in stainless steel, cast iron, hard materials, and non-ferrous metals. The 2-flute parabolic flute geometry promotes efficient chip evacuation, while the web-thinned split point at 130 degrees reduces thrust and helps the bit self-center on entry. Overall length is 2-9/32 inches, with a flute length of 15/16 inches and a maximum drilling depth of 0.6000 inches. This bit suits tool-room machinists, maintenance technicians, and fabricators who need reliable, repeatable performance in short-length drilling operations.

The 5057133 is a Series A1148 screw machine drill bit sized at 11/64 inches (0.1719 inches decimal) with a straight cylindrical shank for use in standard drill chucks and CNC tool holders. The shorter screw machine length body provides added rigidity compared to jobber-length bits, making it well suited for tight-clearance drilling on lathes, drill presses, machining centers, and hand-held power tools. It is rated for universal tool performance across cast iron, stainless steel, hard materials, and non-ferrous metals. The tapered web configuration and parabolic flutes work together to maintain chip flow and reduce heat buildup during extended cutting cycles.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat and wear resistance in hard and abrasive materials
• 130-degree split point with web thinning reduces entry thrust and improves self-centering
• 2-flute parabolic geometry promotes fast, clean chip evacuation
• Screw machine (stub) length body provides greater rigidity than jobber-length alternatives
• Straight cylindrical shank fits standard drill chucks and collet holders
• Meets DIN, ISO, and BS standards; Series A1148 designation for easy cross-reference

Compatibility

Designed as a screw machine length replacement or production drill bit for use in cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Compatible with any drill press, lathe, machining center, or hand-held power tool that accepts a straight cylindrical shank in the 11/64-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool setup and machine operation. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Power down and lock out the machine before changing or inspecting tooling. Do not exceed the material and speed-feed parameters appropriate for HSS cobalt tooling in the workpiece material being drilled.
