The 1\/4 inch hex shank seats directly into standard impact driver chucks without a separate adapter, making it a practical choice for electricians, plumbers, HVAC techs, and mechanical contractors who drill metal on the job. The 135-degree split-point tip reduces walking on contact, allowing clean, accurate starts without center-punching. Jobber length at 4 inches provides the right balance of reach and rigidity for drilling sheet metal, light structural steel, and mechanical enclosures.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for trade work where metal penetration is a regular task — running conduit through sheet metal panels, drilling pipe hangers, punching holes in HVAC plenums, or general metal fabrication. The 1\/4 inch hex shank makes it compatible with the quick-change chucks found on most cordless impact drivers. Its jobber-length geometry fits standard drill configurations without the flex associated with longer aircraft-length bits. Both professionals and experienced DIYers working with metal stock will find this format efficient for repetitive drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting life compared to uncoated HSS bits\u003c\/li\u003e\n  \u003cli\u003eM2 high-speed steel construction maintains hardness under heat generated during metal drilling\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex shank seats in standard impact driver and quick-change chuck systems\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip self-starts on metal surfaces and reduces drill walk\u003c\/li\u003e\n  \u003cli\u003eJobber length at 4 inches balances reach and rigidity for general metal drilling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with impact drivers and drills equipped with a standard 1\/4 inch hex quick-change chuck.

Use appropriate cutting fluid or lubricant when drilling thicker steel stock to manage heat and extend bit life. Allow the bit to cool between uses during prolonged drilling to prevent premature dulling of the TiN coating. Wear appropriate eye protection and secure the workpiece before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 1\/4 inch hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees split-point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 high-speed steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium nitride (TiN)\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: ITM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 255h16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITM","offers":[{"title":"Default Title","offer_id":51525246353714,"sku":"255H16","price":15.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/515e1d390e6a82cb694ecc73ddc31205_e487da95-3934-493b-8aad-06411c3b9ae6.jpg?v=1785468313","url":"https:\/\/voomisupply.com\/products\/itm-255h16-m2-hss-impact-drill-bit-1-4-x-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
