Ground to a 140-degree split point with R-thinned web geometry, it reduces thrust and improves self-centering at entry. The TiAlN coating provides thermal resistance and extended tool life in dry or minimal-lubrication cutting conditions. At 3.70 mm in diameter with a 66 mm overall length, this is a compact, precision ground tool suited to CNC machining centers, drill presses, and production drilling operations. It is sold individually and is appropriate for machinists, tool and die tradespeople, and production floor operators working in steel, cast iron, stainless, and similar materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance machining applications requiring precise, repeatable hole quality in ferrous and non-ferrous metals. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. Coolant-through capability allows internal coolant delivery directly to the cutting zone, making it effective in CNC setups where through-spindle coolant is available. The straight cylindrical shank with a 6 mm shank diameter seats directly in standard ER or Weldon-style collet chucks without adaptation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for thermal protection and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary split point reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces cutting resistance and heat generation at the chisel edge\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole or high-feed applications\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 5xD ratio for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill for use in standard CNC machining centers and drill presses accepting a 6 mm straight cylindrical shank; conforms to DIN specification standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully stopped and locked out per standard LOTO procedures. Seat the straight shank fully and evenly in the collet or chuck before tightening to manufacturer-specified torque for the chuck type in use. Verify runout with a dial indicator before production use, especially in tight-tolerance applications. When using coolant-through capability, confirm that spindle coolant pressure and flow rate are compatible with the drill geometry and workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.70 mm (0.1457 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 66 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 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\u003ePoint Type\u003c\/strong\u003e: Proprietary Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741652320562,"sku":"4500155","price":111.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5a470d1258ab7a501aadb93c1779e69_c810f20e-c05a-414a-8e2b-27debc6177be.jpg?v=1788832740","url":"https:\/\/voomisupply.com\/products\/accupro-4500155-jobber-drill-3-70mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
