Modular drills with replaceable carbide heads for flexible, cost-efficient hole making. Made to order to your drawings.
Replaceable-Head Drilling Systems
Modular drilling systems pair a reusable tool body with replaceable cutting heads — simplifying cutting-edge replacement and supporting flexible hole-making across compatible configurations.
Match the body, head, interface, diameter, and drilling conditions as one system before production use.
Renew the cutting end without replacing the complete tool body when the body and interface remain serviceable.
A compatible body can support multiple replacement cycles, helping reduce full-tool replacement.
A correctly matched head-and-body system can simplify replacement and inventory planning.
Head geometry, grade, and coating can be evaluated for the workpiece and hole requirements.
Provide the required hole diameter and depth, workpiece material, machine connection, coolant method, and any existing body or interface details. JIAYI will confirm the compatible body-and-head combination before quotation.
Open any tool for dimensions and drawings, or request a quote for a modified version.

View ProductsWe are still adding this range to our online catalog. These tools are available made to order: send your drawing or sample and we will quote sizes, lead time and price, or contact our team for current availability.
Tools in this category are produced on request to your drawing, sample or specification. Send us your requirements and our engineers will reply within 24 hours.
Interface consistency. The head-and-body connection is treated as a complete cutting system, not as two independent components.
Inventory efficiency. Replaceable heads can reduce the need to replace complete tools and can simplify stock planning within a compatible system.
Application matching. Geometry, grade, coating, body length, and coolant strategy are reviewed against the actual drilling conditions.
Send the hole requirements, machine interface, current tool information, and workpiece material. Our engineers will review compatibility and propose the body-and-head configuration after technical confirmation.
