NHY
Our custom CNC machined drilling clamp collet is a high-performance precision clamping component engineered for industrial drill presses, CNC machining centers, and automated drilling systems. Crafted from premium alloy steel via advanced CNC turning and slot-milling processes, it features a precision-slotted elastic structure that delivers uniform clamping force and exceptional concentricity, ensuring drill bits and cutting tools remain perfectly aligned even under high-speed, high-torque drilling conditions. Designed to accommodate non-standard tool diameters and thread specifications, this collet offers tailored solutions for precision manufacturing across electronics, automotive, aerospace, and metalworking industries, where consistent hole quality and minimal tool wear are critical.

3.Application Case
A precision electronics manufacturer integrated our drilling clamp collet into a 5-axis CNC center, securing 0.3mm micro-drill bits for PCB hole drilling. The tight concentricity tolerance eliminated drill bit wander, reducing hole position error by 45% and improving PCB yield by 28%.
A metal fabrication workshop utilized our custom drilling clamp collet in a heavy-duty drill press for stainless steel plate drilling. The elastic slotted design provided consistent clamping force under high torque, preventing tool breakage and extending drill bit lifespan by 35% compared to standard collets.
Elastic Slotted Design: Provides uniform clamping force to prevent tool slippage under high torque.
Full Customization: Non-standard bore sizes, thread types, and slot counts are fully customizable.
High Wear Resistance: Alloy steel material extends service life in heavy-duty drilling operations.
Versatile Compatibility: Fits various drill presses, CNC routers, and 5-axis machining centers.
