Built with a 0-degree positive rake angle and a 0.5 inch by 0.5 inch square shank, it accepts TP..22 series inserts held in place by a clamp-type insert holding method. The toolholder measures 4.5 inches in overall length with a head length of 0.75 inches and a back-of-bar to cutting edge distance of 0.5 inches. Constructed from steel, it is intended for use by machinists and tool-and-die professionals in production and job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder suits applications requiring left-hand turning geometry, such as facing toward a tailstock or turning toward a shoulder on the right side of the workpiece. The CTAP style is a standard clamp-type holder configuration common in general-purpose turning setups. It is suited for both roughing and finishing passes when paired with the appropriate TP..22 insert grade. No coolant-through capability is present, so external coolant delivery should be used when chip control or heat management is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand holder orientation for right-to-left turning operations\u003c\/li\u003e\n  \u003cli\u003e0-degree positive rake angle reduces cutting forces on the insert\u003c\/li\u003e\n  \u003cli\u003eClamp-type insert holding method provides secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eAccepts TP..22 series indexable inserts with a 0.25 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and durability in production environments\u003c\/li\u003e\n  \u003cli\u003eSquare shank profile at 0.5 inches by 0.5 inches fits standard tool post and turret pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TP..22 series indexable turning inserts, specifically TP.. 221 as noted in the specification data.

Secure the shank firmly in the tool post or turret pocket to the depth recommended by the machine manufacturer, ensuring the cutting edge height is on center with the workpiece axis. Inspect the insert pocket and clamp components for wear or damage before seating a new insert. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when changing inserts under production conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: CTAP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TP..22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 1000073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727164014898,"sku":"1000073","price":198.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/146f53157c8cc2993a69087fbd380c36.jpg?v=1788674205","url":"https:\/\/voomisupply.com\/products\/hertel-1000073-lh-ctap-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
