Manufactured from high-speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The four-flute geometry provides good chip support and thread form stability in a range of ferrous and non-ferrous materials. With an overall length of 3.813 inches and a thread length of 1.813 inches, this tap is sized for standard M16 threading operations on manual or CNC tapping equipment. Machinists, toolroom technicians, and maintenance trades use this tap where full thread depth to the bottom of a blind bore is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in production machining, job shop threading, and maintenance-repair-operations (MRO) environments. The bottoming chamfer style allows threads to be cut within 1 to 2 pitches of the bottom of a blind hole, making it the correct choice when thread engagement must begin close to the floor of the bore. It is used in steel, cast iron, aluminum, and similar machinable materials where M16x2.00 metric coarse threads are specified. Right-hand thread direction is standard. The D7 thread limit designation indicates the tap is ground to produce threads in the higher tolerance range, supporting applications where some plating or coating of the finished part is anticipated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life versus uncoated HSS\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design provides chip support and thread form stability\u003c\/li\u003e\n  \u003cli\u003eD7 thread limit accommodates post-thread plating or coating allowances\u003c\/li\u003e\n  \u003cli\u003e6H class of fit produces threads within standard metric tolerance for most fastener applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping heads and tap wrenches\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 in blind hole applications.

Ensure the workpiece is securely clamped and the tap is properly aligned to the bore axis before engagement to prevent tap breakage. Apply an appropriate cutting fluid for the workpiece material throughout the tapping operation. For blind holes, clear chips frequently to prevent packing at the bottom of the bore, and never force the tap past its thread length capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16x2.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.360 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: K027782AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728149741874,"sku":"K027782AS25","price":83.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c70a61958cb624a7b283d1db48386d2.jpg?v=1788688838","url":"https:\/\/voomisupply.com\/products\/hertel-k027782as25-straight-flute-tap-m16x2-00-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
