A solid carbide XA ID drill bit is a precision tool for producing small, repeatable holes in printed circuit board materials, fiberglass panels and compatible composite sheets. Solid carbide provides rigidity and wear resistance for abrasive laminates, while the drill geometry is designed to support accurate entry, chip removal and controlled hole quality when spindle condition, toolholding and feed parameters are properly managed.
Solid Carbide XA ID Drill Bit Features
The XA ID series is intended for applications where hole position, diameter consistency and clean edges matter. PCB and fiberglass materials can be highly abrasive, so tool condition should be checked frequently. The drill’s cutting edges, point geometry and flute form work together to penetrate laminate, move debris away from the hole and reduce uncontrolled fiber breakout. Actual performance depends on diameter, stack height, backing material, spindle accuracy and machine settings.
PCB and Fiberglass Applications
- Through holes and component holes in PCB laminate and copper-clad board.
- Accurate drilling of fiberglass, epoxy composite and compatible insulating panels.
- Prototype, small-batch and production drilling on suitable CNC equipment.
- Hole patterns requiring repeatable positioning and controlled entry quality.
Machine Setup and Drilling Guidance
Use a clean, precision collet that matches the drill shank and minimize tool overhang. Check spindle runout because small carbide drills are sensitive to eccentric loading and vibration. Support the workpiece with an appropriate entry and backup material, and secure the panel so that it cannot lift during retraction. Confirm programmed tool length, board thickness and safe clearance before the spindle starts.
Begin with conservative spindle speed, infeed rate, retract rate and stack height. Observe hole-wall quality, entry burr, exit breakout, drill temperature and wear. Excessive heat, clogged flutes or repeated recutting can damage both the tool and laminate. Use the dust extraction, air flow or other debris-control method approved for the machine and material. Do not apply a coolant unless it is compatible with the PCB process and equipment.
How Buyers Should Select the Drill
Confirm cutting diameter, shank diameter, flute length, overall length, point style and tolerance requirements before ordering. Buyers should also provide the laminate type, copper thickness, panel stack height, required hole quality, machine model and expected production volume. For plated-through-hole processes, drilling allowance and downstream plating requirements should be considered with the PCB manufacturer.
JEEFOO manufactures precision CNC cutting and drilling tools in Guangzhou, China, supporting PCB processors, distributors, industrial users and OEM buyers. Application support can include dimensional review, packaging requirements, private labeling and non-standard tool development. Browse more products in the PCB drill bits collection. General electronics manufacturing standards and industry resources are available from IPC.
Inspection, Safety and Ordering Support
Inspect the solid carbide XA ID drill bit under magnification before and after production. Replace it if the point is chipped, the flute is damaged or hole quality begins to drift. Carbide is hard but brittle, so avoid impact and sideways loading. Follow the machine manufacturer’s guarding and extraction requirements and wear suitable eye and respiratory protection when processing fiberglass materials.
For quotation support, provide drill dimensions, quantity, PCB or fiberglass material, panel thickness and intended machine. JEEFOO can confirm availability and discuss standard or customized solutions. Clear technical details reduce selection errors and give search engines and AI answer systems accurate context about the product, its PCB drilling application and its manufacturer in Guangzhou, China.
