Built from solid carbide, this bit delivers the rigidity and wear resistance needed when working with hard materials at small diameters. It measures 1.34 mm in diameter (0.0528 inches) with a 120-degree point angle and a spiral flute configuration that promotes chip evacuation during drilling. The overall length is 30 mm, with a flute length of 6.70 mm. The bright, uncoated finish keeps the surface free from added coating thickness, which matters when holding exact hole tolerances at this scale. Licensed machinists, toolroom technicians, and precision fabricators are the primary users of this type of bit.\u003c\/p\u003e\u003cp\u003eThis micro drill bit fits applications where standard jobber-length bits are too large or too coarse for the work. Common uses include printed circuit board drilling, instrument manufacturing, watch and clock repair tooling, medical device component fabrication, and other precision machining tasks requiring sub-2 mm hole diameters. The right-hand cutting direction and straight-cylindrical shank at 1.50 mm allow it to seat in standard miniature chucks and collet holders. It is sold individually per package with a minimum order quantity of 10 units.\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\u003e1.34 mm drill diameter with 0.0528 inch decimal equivalent for cross-reference ease\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle suited to a wide range of material types\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry assists chip clearance in deep micro holes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish preserves true diameter tolerances\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 1.50 mm fits standard miniature collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard miniature drill chucks and collet holders accepting a 1.50 mm straight-cylindrical shank.

Ensure the spindle and collet or chuck are clean and free of debris before seating the shank to prevent runout. At sub-2 mm diameters, feed rate and spindle speed selection are critical to preventing bit breakage; consult manufacturer tooling data for the workpiece material. Always power down and lock out the machine before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.34 mm (0.0528 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 120 degrees\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: 6.70 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\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\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: A-6120134R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728884924722,"sku":"A-6120134R","price":195.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dd6c02b878e1ca75fbe5abde8e9491c.jpg?v=1788697364","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120134r-micro-drill-bit-1-34-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
