Sized at 1.2188 inches (1-7\/32 inches) in diameter with a 4MT (Morse Taper 4) shank, this bit is built for use in drill presses, lathes, and milling machines equipped with a compatible taper socket or sleeve. The cutting flutes and point are machined from high speed steel with an oxide finish, providing wear resistance during general-purpose metal drilling. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis drill bit fits production and maintenance machining environments where large-diameter holes must be bored with accuracy and control. The 4MT shank seats directly into compatible spindle tapers, eliminating the need for a chuck and reducing runout. Typical applications include fabrication shops, tool rooms, and maintenance facilities drilling through steel plate, cast iron, or similar structural materials. The right-hand spiral flute and web-thinned point help reduce thrust and improve chip evacuation in through-hole drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.2188 inches (1-7\/32 inches) diameter for large-bore hole applications\u003c\/li\u003e\n\u003cli\u003e4MT taper shank for direct spindle mounting without a chuck\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip to reduce cutting thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for wear and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute for efficient chip removal\u003c\/li\u003e\n\u003cli\u003e13.125-inch overall length with 7.5-inch flute length for deep-hole reach\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards for taper shank drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, lathes, and milling machines fitted with a 4MT (Morse Taper 4) spindle socket or compatible sleeve adapter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before seating or drifting the taper shank. Clean both the shank taper and the spindle socket thoroughly before insertion to ensure full metal-to-metal contact and prevent fretting. Use a proper drift key and drift slot to remove the bit safely — never strike the spindle housing directly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1.2188 inches (1-7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.5 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 209\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6001109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51690779443506,"sku":"6001109","price":210.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91f3c7609b9c9ca5a8425dc07c240c2d_6de70a13-5e69-4fec-806f-88461a94659a.jpg?v=1788275489","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001109-taper-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
