Hot Q&A

Q1: What inserts are compatible with this SP series U drill?
A1：It is specially matched with SPMG series square carbide inserts, including SPMG050204, SPMG060204, SPMG07T308, SPMG090408, SPMG110408. Inserts for steel, stainless steel and cast iron are optional.

Q2: What do 2D/3D/4D/5D mean for the U drill?
A2：D refers to the drill bit diameter. Drilling depth = Diameter × Ratio. For example, a 20mm U drill: 2D=40mm depth, 3D=60mm depth, 4D=80mm depth, 5D=100mm depth.

Q3: Can this U drill drill stainless steel?
A3：Yes. Equipped with professional stainless steel-grade coated SPMG inserts, it can drill stainless steel, 40Cr and other hard alloy materials stably and efficiently.

Q4: Does this drill support internal cooling?
A4：Yes. It adopts double spiral internal cooling holes, which connects with machine tool coolant system to realize efficient heat dissipation and chip removal.

Q5: What is the MOQ and delivery time?
A5：Standard models support 1PC MOQ. Customized orders depend on requirements. Stock goods can be delivered in 7-15 days, customized orders take 15-30 days.
