Built from solid carbide, it delivers the rigidity and heat resistance needed for drilling in harder materials where high-speed steel tooling falls short. The 140-degree point angle promotes self-centering and reduces thrust force at entry. With an overall length of 66 millimeters, the stub-length body provides added stiffness and minimizes deflection in short-reach setups. This bit is intended for use in CNC machining centers, drill presses, and turret lathes operated by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are well suited for production environments where rigidity matters more than reach. The compact overall length makes this bit a practical choice for drilling in fixtures, jigs, and tight work envelopes common in metal fabrication shops. The right-hand spiral flute geometry promotes chip evacuation during through-hole and blind-hole drilling in ferrous and non-ferrous metals. The straight cylindrical shank is compatible with standard drill chucks and collet holders across a wide range of machine tool spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior rigidity and wear resistance compared to high-speed steel\u003c\/li\u003e\n\u003cli\u003e140-degree split-style point angle for self-centering and reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStub screw machine length body minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eSeries R458 designation for straightforward replacement and tooling catalog reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length drill bit for use in metalworking drill presses, CNC machining centers, and turret lathes equipped with compatible straight-shank chuck or collet toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and serviced by machinists or qualified machine tool operators. Ensure the machine spindle is fully stopped and the tool is de-energized before changing tooling. Secure the straight shank firmly in the chuck or collet to the manufacturer-specified clamping torque using appropriate toolholding hardware. Inspect the cutting edges for wear or chipping before each use, and replace the bit when edge condition degrades to prevent workpiece damage or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 15\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R458\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DORMER PRAMET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5980494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORMER PRAMET","offers":[{"title":"Default Title","offer_id":68295857537330,"sku":"5980494","price":85.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25b2f73c689b40e0505d268c201bd47f_f032d102-1143-408f-8ed2-ea235bfc5394.jpg?v=1793698105","url":"https:\/\/voomisupply.com\/products\/dormer-pramet-5980494-screw-machine-drill-bit-15-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
