Featuring a rare and highly strategic \u003cstrong\u003e7mm precision cylindrical clamping shank\u003c\/strong\u003e and a 125mm tool length (K-type standard), this unique holder bridges the critical gap between standard 6mm and 8mm bars. It offers the high mechanical rigidity required to suppress tool deflection while fitting into micro-cavities where an 8mm shank would suffer tool-post interference. By incorporating the specialized \u003cstrong\u003eS-type Screw Fastening system\u003c\/strong\u003e, the insert is secured firmly through its center hole without bulky upper clamps. This creates a completely flush head profile and an unobstructed chip flute pathway, making it highly exceptional for small-diameter machining where micro metal swarf accumulation would otherwise trap heat, score the bored wall, and cause catastrophic edge chipping.\u003c\/p\u003e\n\u003cp\u003eWith its engineered 75-degree approach lead angle (K-type geometry), the pocket alignment balances cutting forces smoothly between axial and radial axes, shifting pressure away from the workpiece to eliminate micro-chatter on high-aspect-ratio bores. It is custom-machined to host standard positive 7-degree relief 80-degree diamond indexable inserts, specifically the globally interchangeable \u003cstrong\u003eCCMT 060202 \/ CCMT 060204 \/ CCMT 060208\u003c\/strong\u003e series. This positive geometry ensures a razor-sharp shearing action, low cutting resistance, and minimal thermal generation on the workpiece matrix. The compact screw-down head allows this 7mm tool holder to clean micro bores down to an optimized \u003cstrong\u003e9.5mm minimum bore diameter\u003c\/strong\u003e. When paired with targeted positive chipbreaker geometries (such as polished -AL profiles for non-ferrous aluminum or moulded -PM\/-HMP profiles for carbon steels), it tightly curls long swarf ribbons into crisp \"C\"-shaped chips, pushing them smoothly out of the narrow bore channel to preserve mirror-like surface integrity and tight dimensional tolerances.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 20px; margin: 25px 0; background-color: #fbfbfe;\"\u003e\n\u003ch3 style=\"margin-top: 0; color: #47479f; font-size: 16px; border-bottom: 1px solid #e0e0e0; padding-bottom: 8px;\"\u003eModel Nomenclature Decoder: S07K-SCKCR06 (ISO \/ National Standard Chart Compliant)\u003c\/h3\u003e\n\u003cdiv style=\"margin-top: 12px; font-family: monospace; font-size: 13px;\"\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e - Solid High-Tensile Structural Alloy Steel Body Core (No through-coolant hole)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003e07\u003c\/strong\u003e - 7mm Precision Cylindrical Clamping Shank Diameter (Strategic size maximizing rigidity in tight setups)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eK\u003c\/strong\u003e - 125mm Industrial Standard Total Tool Core Length (Precision micro-reach specification)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; color: #333333;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e - \u003cstrong\u003eScrew Fastening Method\u003c\/strong\u003e (Streamlined profile, opens maximum chip clearance room for tight internal cuts)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eC\u003c\/strong\u003e - 80° Diamond Geometric Positive Insert Shape Pocket Seating (CCMT 0602 format)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; color: #333333;\"\u003e\n\u003cstrong\u003eK\u003c\/strong\u003e - \u003cstrong\u003e75° Approach Lead Angle\u003c\/strong\u003e (Reduces radial deflection forces for highly stable micro-profiling)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003eC\u003c\/strong\u003e - \u003cstrong\u003e7° Normal Positive Relief Clearance Angle\u003c\/strong\u003e (Sharp micro-cutting edge layout providing ultra-low tool pressure)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003eR\u003c\/strong\u003e - \u003cstrong\u003eRight-Hand Tool Cutting Rotation Direction\u003c\/strong\u003e (Standard forward M03 internal turning toolpath setup)\u003c\/div\u003e\n\u003cdiv style=\"display: block; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003e06\u003c\/strong\u003e - Accommodates Standard 6mm Cutting Edge Length Inserts (CCMT 060202 \/ CCMT 060204)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 15px; margin-bottom: 25px; background-color: #47479f; color: #ffffff; text-align: center;\"\u003e\n\u003cp style=\"margin: 0 0 10px 0; font-weight: bold; font-size: 16px;\"\u003eOperating reverse profiling cycles or left-hand toolpaths on sub-spindles?\u003c\/p\u003e\n\u003cspan style=\"color: #47479f;\"\u003e\u003cspan style=\"display: inline-block; background-color: rgb(255, 255, 255); padding: 8px 20px; border-radius: 4px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cb\u003e \u003ca href=\"https:\/\/cnchome-beyond.com\/search?q=CCMT0602\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S07K-SCKCL06 (Left Hand) Tool Bar → \u003c\/a\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e2.

When boring deep micro-holes, a 6mm steel bar often lacks the torsional stiffness required, leading to chatter. However, an 8mm bar might hit the inner bore wall or fail to clear the lathe's internal tool-post structure. The 7mm shank maximizes steel mass for rigidity while fitting into tighter entry zones.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px; padding: 12px; background-color: #f9f9f9; border-radius: 4px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ2: What is the absolute minimum bore entry size for this S07K-SCKCR06 tool holder?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA2: The minimum machining bore diameter (φ Dmin) is exactly 9.5mm (0.374 inches). Attempting to operate this boring bar inside any hole smaller than 9.5mm will cause the steel clearance flank located directly beneath the pocket seat to rub against the workpiece wall, causing frictional heat, chatter, and part damage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px; padding: 12px; background-color: #f9f9f9; border-radius: 4px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ3: How does the 75-degree lead angle protect the delicate 7mm bar from flexing?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA3: Slender tool bars flex easily when subjected to high radial (side-to-side) forces. A 75° approach angle re-directs a significant portion of the cutting force axially along the length of the tool holder straight back into the rigid tool turret. This minimizes radial deflection, keeping the bar straight and stable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e9.
