The SK30 tool holder is a high-precision spindle tooling solution designed for demanding CNC Machining applications. Engineered with advanced manufacturing techniques and strict quality standards, the SK30 CNC tool holder ensures superior accuracy, excellent clamping force, and long-lasting durability. Its standard SK30 taper makes it compatible with a wide range of milling and machining centers, making it ideal for precision metalworking, mold manufacturing, and aerospace components. The SK30 collet holder supports various cutting tools including drills, end mills, and reamers, offering versatile and reliable performance.

The SK30 tool holder is precision-ground with tight tolerances to maintain minimal runout, typically ≤0.005 mm. This ensures stable and repeatable tool positioning, reducing vibration and improving machining surface quality, even under high-speed operations.
Equipped with high-quality collets, the SK30 collet holder provides strong and secure clamping for tools of different diameters. This reduces tool slippage and ensures consistent machining performance, which is critical for precision manufacturing.
Made from hardened and heat-treated steel, the SK tool holder SK30 resists wear, corrosion, and deformation. Advanced surface treatments enhance durability, allowing the tool holder to maintain peak performance over prolonged use.
The SK30 CNC tool holder is compatible with multiple ER collet sizes and supports a wide range of cutting tools. It can be used across different CNC machines and milling centers, providing flexibility for various machining tasks.
