The Bt40-Er25-100 High Precision Tool Holder is a CNC accessory that combines a BT40 taper interface with an ER25 collet chuck, providing a 100 mm long body for extended reach. It is machined from high‑grade tool steel, specifically a chrome‑molybdenum alloy, and hardened to a typical 56‑60 HRC to deliver long service life under demanding cutting conditions. The holder features a rear M16 × 2.0 thread for pull‑stud attachment and a nickel‑plated surface that improves corrosion resistance and aesthetic durability.
Run‑out is tightly controlled at 0.002 mm, and the tool holder meets the AT3 accuracy standard for BT40 tapers, ensuring minimal spindle vibration at high speeds. Balanced to a G2.5 grade at 20 000 rpm, the holder maintains rigidity during heavy machining, making it suitable for precision mould making, automotive component production and high‑speed milling. The nickel coating further protects the hardened steel from rust, while the standard protective packaging safeguards the item during international transit.
The tool holder is marketed to manufacturers that require exacting dimensional stability and repeatable performance from their CNC equipment. Qufu Chongde offers export‑ready units with typical FOB or CIF terms, and mentions ISO‑9001 certification as part of its quality system, though specific certificates must be requested. No fixed minimum order quantity is disclosed, so buyers should discuss volume expectations directly with the supplier. Confirming lead‑time, payment conditions and any required documentation will streamline the import process.

Prior to ordering, ask the supplier for a material test report confirming the chrome‑molybdenum composition and the achieved hardness of 56‑60 HRC. Verify the run‑out measurement of 0.002 mm and the AT3 taper compliance with a calibrated gauge, especially if your machines operate at high spindle speeds. Obtaining a copy of the ISO‑9001 certificate will also support your internal quality‑assurance procedures.
Discuss the preferred Incoterm - FOB or CIF - and confirm the exact lead‑time based on your required delivery schedule. Because the supplier’s response rate is currently zero, establish a reliable point of contact early and clarify payment terms, such as a letter of credit or advance payment, before finalising the contract. Align the shipping method with your logistics network to avoid unexpected delays at port.
When the tool holders arrive, conduct a visual inspection for coating integrity, check the M16 thread for correct pitch, and perform a dimensional verification of the 100 mm body length. A functional test on a sample machine will confirm the 0.002 mm run‑out and balance performance. Retain all inspection reports and the supplier’s certification documents as part of your import compliance records.
