Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS. The cutting diameter is 1 inch, the overall length (OAL) is 6 inches, and the flute length is 2.25 inches. The straight-cylindrical shank measures 1 inch in diameter for direct chuck or toolholder engagement. This is a single-ended, right-hand cut tool suited for general-purpose metalworking applications.\u003c\/p\u003e\n\u003cp\u003eThe 6000135 is used in production machining, tool-and-die, and maintenance-repair operations where precise hole location is required before drilling, reaming, or tapping. The 90-degree included angle aligns with standard countersink geometry and is compatible with conventional drill press, CNC machining center, and manual lathe setups. Its spiral flute design promotes chip evacuation during the spotting operation. Machinists, tool-and-die makers, and maintenance technicians working with ferrous and non-ferrous metals are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree drill point angle for accurate spot and chamfer alignment\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e1-inch cutting diameter with 2.25-inch flute length for adequate chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1-inch shank fits standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, single-ended, Series SPSG-90 — two spiral flutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spotting drill for use in drill press, CNC machining center, and manual lathe applications requiring a 1-inch diameter, 90-degree spot or chamfer on ferrous and non-ferrous workpieces.

Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Always wear appropriate personal protective equipment including eye protection when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPSG-90\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6000135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720694432050,"sku":"6000135","price":216.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8faf6eff03b25dd37b34d9e5a40f7d07.jpg?v=1788567816","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000135-spotting-drill-90-deg-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
