RONGKE offers 3D Solid Carbide Three Flute Micro Drill Bits for short-hole CNC machining. Manufactured in China, the DS303C range combines a compact body with three cutting edges and diameters from Ø5.0 to 12.0 mm. Request a factory quotation for standard sizes or a review of your non-standard drawing.

For a matched center-and-periphery drilling assembly, RONGKE Modular Large Diameter Phoenix Combined Drill supports selection around the center tip and peripheral insert combination. Contact us for wholesale enquiries. Choose W/WOMT or Z/ZPMT from the matched head and body tables. Request the full assembly reference so center diameter, outer pockets and connection are selected together.

When an MDD assembly needs additional reach, RONGKE Modular Deep Hole Drill Extension supports selection around the locating diameters at both ends of the YXZ extension. Contact us for supplier quotations. They are distinct from DXZ machine-side connecting shanks. Order by both locating diameters and the applicable MDD head group, not length alone.

For large-hole work with diameter adjustment, RONGKE MDD Modular Deep Hole Drill Bits supports selection around the adjustment interval of the selected modular head. Contact us for spare-tip quotations. The catalog states 0–5 mm diameter adjustment within the selected head group. Request the diameter interval, pilot and modular reach components together.

HSS 60 Degree Center Drill Bits from RONGKE are made for preparing center holes in shafts, pins and turned components before center-supported machining. The DIN 333 Form A reference design combines a pilot drill with a 60° centering cone, while separate pilot and body diameters allow the tool to be selected around the required center-hole configuration. RONGKE supplies standard sizes from 1.00 to 4.00 mm pilot diameter and can also evaluate non-standard cutting-tool requirements for different machining applications.

For buyers who need a larger drilling diameter without a correspondingly large chuck capacity, RONGKE HSS Reduced Shank Twist Drill Bits offer a practical tooling configuration. The drill has a cutting diameter larger than its cylindrical shank, with reference sizes from 14 mm to 20 mm, using 10 mm or 13 mm reduced shanks. Based on the DIN 338 length family, the drills feature a 118° split point and are intended for general metal drilling where the existing machine and holder can accommodate the reduced shank.
