Featuring a \u003cstrong\u003e10mm precision-ground solid alloy steel shank\u003c\/strong\u003e with a 125mm overall length (K-type standard), this tool core is vacuum-hardened to achieve superior static stiffness and structural dampening, drastically suppressing the harmonic chatter generated at long overhang ratios. The primary technological edge of this holder lies in its \u003cstrong\u003e95° lead approach angle (Z-Type geometry)\u003c\/strong\u003e combined with an \u003cstrong\u003eS-type Screw Clamping system\u003c\/strong\u003e. By securing a 7° positive 55-degree diamond insert via a high-tensile central Torx screw directly into a precision-milled pocket, it eliminates bulky top bridges, providing an completely unhindered path for high-velocity swarf evacuation, maintaining a strict minimum \u003cstrong\u003ebore entry diameter of 13.0mm\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eTailored to host standard 55-degree indexable diamond \u003cstrong\u003eDCMT 070202 \/ DCMT 070204\u003c\/strong\u003e or ultra-sharp \u003cstrong\u003eDCGT 070202\u003c\/strong\u003e carbide inserts, this tool pocket ensures rigid flank seating and precise center-height tracking. When paired with advanced sharp-ground chipbreaker geometries—engineered for immediate curling and chip-snapping in tight spaces—the tool system effectively minimizes radial cutting pressure.

The core operational advantage of this holder is its low-profile \u003cstrong\u003eS-type Screw Clamping mechanism\u003c\/strong\u003e. By fastening the 55-degree rhombic insert directly through its counter-sunk center hole with a high-tensile Torx screw, the tool head maintains an exceptionally sleek footprint.

The 93° layout is mathematically optimized to balance axial and radial cutting forces, transferring harmful micro-vibrations straight down the longitudinal core of the steel shank to eliminate chatter during fine finishing sweeps.

The core operational advantage of this holder is its low-profile \u003cstrong\u003eS-type Screw Clamping mechanism\u003c\/strong\u003e. By fastening the 55-degree rhombic insert directly through its counter-sunk center hole with a high-tensile Torx screw, the tool head maintains an exceptionally sleek footprint.

Forged from high-tensile, vacuum-hardened alloy steel, this tool holder delivers exceptional cross-sectional density and structural stiffness within a highly compact 10mm shank matrix. Specially optimized for tight internal bores with a minimum clearance diameter of 13mm, it features a precision-machined insert pocket tailored to perfectly seat \u003cstrong\u003eDCMT 0702-- indexable carbide inserts\u003c\/strong\u003e (such as DCMT 070204 or DCMT 070202).\u003c\/p\u003e\n\u003cp\u003eBy pairing this tool holder with positive rake indexable inserts engineered with targeted chipbreaker channels, the assembly effectively absorbs radial cutting forces to halt catastrophic tool vibration and micro-chatter. The precise geometry of the insert pocket maintains the exact tool presentation angle, allowing the insert’s chipbreaker to curl and snap continuous metal swarf into tight, manageable segments. This prevents dangerous chip nesting within narrow cavities, ensuring scratch-free internal surfaces and securing high dimensional repeatability across dense manufacturing runs.\u003c\/p\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e2.

Forged from high-tensile, vacuum-hardened alloy steel, this tool holder delivers exceptional cross-sectional density and structural stiffness within a highly compact 14mm shank matrix. Specially optimized for tight internal bores with a minimum clearance diameter of 17mm, it features a precision-machined insert pocket tailored to perfectly seat \u003cstrong\u003eDCMT 0702-- indexable carbide inserts\u003c\/strong\u003e (such as DCMT 070204 or DCMT 070202).\u003c\/p\u003e\n\u003cp\u003eBy pairing this tool holder with positive rake indexable inserts engineered with targeted chipbreaker channels, the assembly effectively absorbs radial cutting forces to halt catastrophic tool vibration and micro-chatter. The precise geometry of the insert pocket maintains the exact tool presentation angle, allowing the insert’s chipbreaker to curl and snap continuous metal swarf into tight, manageable segments. This prevents dangerous chip nesting within narrow cavities, ensuring scratch-free internal surfaces and securing high dimensional repeatability across dense manufacturing runs.\u003c\/p\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e2.

For this 10mm bar, that equals a maximum stable reach of 30mm. Extending the bar beyond this threshold increases elastic deflection and causes severe surface finish chatter.

Machined from ultra-clean, vacuum-hardened alloy steel, this tool holder provides exceptional rigidity and natural harmonic dampening. This reduces tool chatter during extended-reach operations inside medium-sized bore openings down to a minimum clearance diameter of 20mm.

Built from premium-grade, vacuum-hardened alloy steel, the robust 12mm shank diameter provides excellent torsional stiffness to prevent structural deflection during deep-reach roughing and finishing passes. This industrial tool holder allows highly accurate tool paths inside medium-to-small bore openings down to a minimum clearance diameter of 16mm.
