Built from solid carbide and coated with an AlTiN finish, this bit delivers excellent heat and wear resistance at elevated cutting speeds. It features a 140-degree point angle for aggressive, self-centering penetration into hard materials. With an overall length of 2.44 inches and a 1\/8 inch (0.1250 inch) cutting diameter, this stub-length design provides added rigidity compared to jobber-length bits, reducing deflection in short-hole drilling operations. Licensed machinists, tool-and-die professionals, and precision metalworking technicians are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, and high-temperature alloys in production machining environments. The screw machine length format makes it well-matched for CNC machining centers, turret lathes, and manual knee mills where short-reach tooling is required. The straight cylindrical shank at 0.2362 inch (6.00 mm) diameter seats securely in standard drill chucks and collet holders. The flute-by-diameter ratio of 3xD supports chip evacuation in through-hole and blind-hole work within its rated maximum drilling depth of 0.55 inches. The coolant-through design enables internal coolant delivery to the cutting zone, extending tool life when used with appropriate coolant-capable spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with AlTiN coating for heat resistance and long tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for self-centering entry and reduced thrust in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides superior rigidity and reduced deflection over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes efficient chip evacuation at a 3xD flute-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eCompliant with DIN 6535 and DIN 6537 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 0.2362 inch (6.00 mm) straight cylindrical shank.

Ensure the spindle and workpiece are fully secured and the machine is at a complete stop before inserting or removing the bit from the chuck or collet. Carbide tooling is brittle and susceptible to chipping from lateral shock or improper clamping  -  never use excessive side force. When using the coolant-through feature, verify that the machine spindle is configured to deliver coolant at the appropriate pressure before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch \/ 3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.44 inches (62.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.787 inches (20.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.55 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.019 inches (0.47 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCMS15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 x 0.39 x 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6358124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742462738738,"sku":"6358124","price":239.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccc4eb574fb7b8e724fde9bf5fb93fd3_9a957c7e-050e-41c2-a0c3-ebcc1a99f832.jpg?v=1788837634","url":"https:\/\/voomisupply.com\/products\/kennametal-6358124-screw-machine-drill-bit-1-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
