• Material: Tungsten carbide

• Type: Solid carbide

• Shank: Reinforced, Ø 3.17 mm (1/8″)

• In stock: Cutting diameters from Ø 0.3 mm to 3.00 mm

• Minimum drilling speed: 20,000 rpm

• The smaller the drill bit diameter, the higher the required speed

• Feed rate: 1.6 to 4 m/min

• Optional: Drill bits with stop rings available upon request

To prevent excessive heat during drilling, it is recommended to adjust the feed rate according to the spindle speed and drill bit diameter. Both cutting speed and feed rate are important for achieving good drilling results. The PCB panels must be securely held in place during drilling.

Cutting Speed (m/min) = (d × 3.14 × RPM) / 1000\
(where d is the drill bit diameter in mm)

Spindle Speed (RPM) = (Cutting Speed × 1000) / (d × 3.14)

Feed per Revolution (µm/rev) = (Feed Rate (mm/min) × 1000) / RPM
