Triumph Twist Drill 060419 Screw Machine Drill Bit 19/64

Product Description

The TRIUMPH TWIST DRILL 060419 is a screw machine length drill bit designed for heavy-duty metal cutting in industrial and trade applications. Built from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web configuration that reduces walking and improves hole entry on hard materials. At 19/64 inch (0.2969 inches) diameter with a 2.75-inch overall length and 1.5625-inch flute length, it fits standard drill chucks and screw machine setups. The right-hand spiral flute design promotes efficient chip evacuation. Machinists, tool-and-die tradespeople, and maintenance technicians reach for this bit when drilling through PH steel and superalloys.

The 060419 is suited for screw machine operations, CNC drilling fixtures, and bench drill press work where a stubby, rigid bit length is preferred over jobber length. Its shorter body reduces deflection in deep-hole setups and tight clearance situations. The T4HD series targets heavy-duty applications where standard-grade bits wear prematurely, making this bit appropriate for production drilling in stainless, precipitation-hardened steel, and high-temperature superalloy components.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metal cutting operations.
