Manufactured from high speed steel with a TiN (titanium nitride) coating, this tap delivers increased surface hardness and wear resistance compared to uncoated HSS tooling. The bottoming chamfer — typically 1 to 2 threads of lead — allows threading to the bottom of blind holes with minimal runout clearance. With an overall length of 3-13\/16 inches and a thread length of 1-13\/16 inches, it is sized for standard machine and hand-tapping applications in a range of workpiece materials. A licensed machinist or tool-and-die technician is the typical user.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for metric coarse threading operations on ferrous and non-ferrous metals in manufacturing, maintenance, and repair environments. The D4 thread limit designates a tolerance class appropriate for standard fit metric fasteners. The 4-flute straight-flute geometry handles chip evacuation in through-hole applications and in shallow blind holes where chip packing is managed by periodic retraction. It is intended for use with a standard tap wrench, tapping head, or machine spindle operating at appropriate low-torque feed rates for M16 threading.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes with minimal clearance\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eD4 thread limit suits standard metric coarse fit requirements\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design for controlled chip evacuation in through-hole and shallow blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard metric coarse fastener profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting M16x2.00 metric coarse right-hand internal threads.

Before tapping, ensure the drilled hole is sized to the correct M16 metric coarse tap drill diameter per standard reference tables. Use appropriate tapping fluid or cutting oil for the workpiece material to reduce friction and extend tap life. When tapping blind holes with a bottoming tap, clear chips frequently by reversing the tap to prevent chip packing and tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16 x 2.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.3600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K020346AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729155621170,"sku":"K020346AS25","price":233.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/955b00e7affc548303bf29e352a63fbe.jpg?v=1788701022","url":"https:\/\/voomisupply.com\/products\/hertel-k020346as25-hand-tap-m16x2-00-bottoming-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
