With a 1 mm cutting diameter and a 120-degree point angle, it produces accurate entry points and clean through-holes in hard and abrasive materials. The bright, uncoated finish makes it well suited for use in materials where coating adhesion or thermal buildup is not a concern. The straight-cylindrical shank at 1.50 mm diameter seats securely in standard collet chucks and micro drill chucks. An overall length of 30 mm keeps the tool compact and rigid, reducing deflection during high-speed drilling operations. Machinists, tool-and-die makers, and PCB fabricators commonly specify this bit for work requiring tight positional accuracy at sub-2 mm diameters.\u003c\/p\u003e\u003cp\u003eThis micro drill bit fits into light-duty CNC machining centers, benchtop drill presses, and hand-held precision drilling stations used in electronics manufacturing, watchmaking, medical device fabrication, and instrument tooling. The 8 mm flute length accommodates shallow to moderate-depth holes appropriate to the 1 mm diameter. Right-hand spiral flutes clear chips efficiently without the need for through-coolant, keeping the setup simple. It is sold individually with a minimum order quantity of 10 units, making it practical for shop stocking or production runs where bit replacement is routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 mm cutting diameter with 0.0394 inch decimal equivalent for dual-unit reference\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate self-centering on entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides hardness and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating delamination risk in sensitive applications\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute evacuates chips without through-coolant\u003c\/li\u003e\n\u003cli\u003eCompact 30 mm overall length minimizes deflection in precision setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-stock micro drill bit for use in standard collet chucks and micro drill chuck systems that accept a 1.50 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of micro drill bits should be performed by a qualified machinist familiar with small-diameter tooling. Always power down and lock out the spindle before inserting or removing the bit from the chuck. Ensure the collet or chuck is clean and undamaged before seating the shank, as runout at this diameter magnifies rapidly with any chuck contamination. Do not exceed the manufacturer-recommended spindle speed range for 1 mm carbide tooling, and inspect the cutting edge under magnification before each use to confirm it is free of chips or micro-fractures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.75 inches x 2.25 inches x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: A-6100100R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744642892082,"sku":"A-6100100R","price":230.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e995372279e6c495ace5039046276c2.jpg?v=1788859383","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100100r-micro-drill-bit-1-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
