It features a 27\/64-inch diameter cutting edge ground to a 118-degree standard point angle with web thinning to reduce thrust and improve chip evacuation at drill entry. The shank is machined to a No. 1 Morse Taper (1MT) for direct mounting in compatible drill press spindles and milling machine quills. Manufactured from high-speed steel (HSS) with an oxide finish, the C12170 is built to handle the heat and abrasion typical of production and maintenance drilling operations. Cutting direction is right-hand with a regular spiral flute pattern.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use in machine shop, maintenance, and fabrication environments where a Morse taper spindle is the standard toolholding interface. The 3.875-inch flute length provides adequate chip clearance for deep-hole applications relative to its diameter. At 7.25 inches overall length, it fits standard No. 1 Morse taper drill press spindles used in light industrial and trade settings. Machinists, millwrights, and tool-room technicians will find this bit appropriate for moderate-volume hole-making in ferrous and non-ferrous stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64-inch diameter (0.4219 inches decimal equivalent) with a tight tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003eNo. 1 Morse Taper shank for direct spindle mounting without a separate chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute for reliable chip removal\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling for drill presses, lathes, and milling machines equipped with a No. 1 Morse Taper (1MT) spindle or tailstock socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a No. 1 Morse Taper spindle or sleeve; ensure the taper socket is clean and free of chips or burrs before seating the shank. Power down and lock out the machine before inserting or removing the bit. Use a drift key and the spindle's drift slot to eject the bit safely — do not strike the bit directly. Verify spindle speed is appropriate for the workpiece material and bit diameter before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inches (0.4219 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper\u003c\/strong\u003e: 1MT (No. 1 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard with web thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2410\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C12170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51689644130610,"sku":"C12170","price":68.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_135435ee-ebc8-4fef-9ac0-f4ed383aa71d.jpg?v=1788262316","url":"https:\/\/voomisupply.com\/products\/cleveland-c12170-taper-shank-drill-bit-27-64-in-1mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
