Built to Series DB133-08-A1 specifications, it features an AlCrN coating for extended tool life and heat resistance at high cutting speeds. The drill measures 0.0472 inches in diameter with a 140-degree point angle, a flute length of 0.551 inches, and an overall length of 2.126 inches. A through-coolant design channels cutting fluid directly to the tip, reducing heat buildup and evacuating chips efficiently. Right-hand cut geometry and a straight-cylindrical shank make this drill compatible with standard collet and chuck systems. Machinists and tool room technicians are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for blind hole, stack drilling, and through-hole drilling operations. Its primary target materials include cast iron, non-ferrous metals, stainless steel, and steel. Secondary compatible materials include cobalt, glass, graphite, iron alloys, nickel, titanium, and titanium alloys. With a maximum drilling depth of 12.00 mm and an 8xD flute-by-diameter ratio, it handles deep, tight-tolerance bores where chip clearance and thermal management are critical. The shank diameter is 0.118 inches, conforming to DIN 6535 HA standards for precise spindle seating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrN coating provides oxidation resistance and extends cutting life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant channel delivers fluid directly to the cutting edge for thermal control and chip evacuation\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves centering on hard and layered materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity at micro diameters where high-speed steel would deflect\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank conforms to DIN 6535 HA for secure, concentric clamping\u003c\/li\u003e\n  \u003cli\u003e8xD flute ratio supports deep-hole drilling relative to bit diameter with controlled chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind hole, stack drilling, and through-hole applications on cast iron, non-ferrous metals, stainless steel, steel, cobalt, glass, graphite, iron alloys, nickel, titanium, and titanium alloys.

Verify spindle runout before seating the shank, as even minor concentricity errors are amplified at 0.0472 inches diameter and can cause tool breakage. Ensure through-coolant supply is active and at adequate pressure before engaging the cut. Never force-feed a micro drill bit — use programmed feed rates appropriate to the workpiece material and consult the machine tool manufacturer for recommended spindle speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.551 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DB133-08-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6535 HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.19 x 0.47 x 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7577879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51752487223602,"sku":"7577879","price":298.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ea29462809c4e4a6ad92f5bfd40516b_1d8c45a2-a9cd-4806-9ef2-5ab03e464526.jpg?v=1788928521","url":"https:\/\/voomisupply.com\/products\/walter-titex-7577879-micro-drill-bit-0-0472-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
