HSK50A/63A/100A END MILL HOLDER

Side fixed SLA (dedicated for straight shank vertical milling, preferred for rough machining)

1.Principle: The side top thread directly locks the straight shank milling cutter, without cylinder clamp, with huge clamping force and no slipping

2.Clamping range: Φ 6~Φ 32mm

3. Advantages: The strongest rigidity, resistance to heavy cutting, simple maintenance, and wear resistance

4. Applicable: tungsten steel end mills, white steel knives, large surplus roughing, stainless steel/mold steel processing

General parameters for material and precision (unified standard for the entire series)

1. Material: 20CrMnTi carburizing and quenching, HRC56~60， Carbonized layer ≥ 0.8mm, rust resistant and wear-resistant

2. Cone tolerance: AT3 level; True roundness<0.8 μ m, surface roughness Ra<0.5 μ m

3. Factory dynamic balance: standard G6.3; High speed demand can be customized G2.5/G1

4. Repetitive positioning accuracy: ≤ 2 μ m, axial/radial rigidity better than BT tool holder by 30%+

5. Cooling: Supports spindle center water outlet+flange end water outlet, excellent deep cavity chip removal

FAQ:

Q1: What is the difference between HSK-A, HSK-E and HSK-F?

• HSK-A: Has drive keyways. Transmits high torque. Best for general milling, roughing & semi-finishing. Most widely used.

• HSK-E: No keyways, fully symmetrical. Excellent dynamic balance for ultra-high speed, light cut precision finishing. Torque capacity is lower.

• HSK-F: Same symmetrical keyless design as HSK-E. Same flange size as HSK-E of the same code, but smaller taper. Larger flange contact area for better rigidity in high-speed light machining.

Q2: Is HSK holder compatible with BT spindle?

     A: No. HSK and BT have different spindle interfaces, cannot interchange. Match HSK type (A/E/F) to your machine spindle.

Q3: What balance grade do I need for HSK end mill holder?

A: G6.3 for <15000 RPM; G2.5 for high speed above 15000 RPM to reduce vibration.

Q4: What runout can your HSK end mill holder achieve?

A: ≤0.003mm at 3xD, stable for precision milling.

Q5: Can I use scratched HSK taper holder?

A: No. Even tiny scratches on taper/flange cause runout and damage spindle. Keep contact surface clean.

Q6: What HSK types are available for end mill holders?

A: HSK40A, HSK50A, HSK63A, HSK100A, HSK-E/F available. Custom lengths acceptable.

Q7: What is the lead time?

A: Standard sizes in stock, 3–7 days delivery. Custom holders 7–15 days.

Q8: Do you offer warranty?

A: Yes. Warranty against manufacturing defects.
