Face milling is one of the most common and demanding operations performed on manual milling machines (such as Bridgeport-style knee mills) and conventional boring mills. To achieve flat surfaces and high material removal rates without chatter, the connection between the machine spindle and the large-diameter face mill must be absolutely rigid. The DIN 2080 NT FMB Face Mill Holder provides this critical connection. Designed with a robust, single-piece forged body, it features a precision-ground metric pilot (the "FMB" spigot) and heavy-duty drive keys that engage the slots on the back of the face mill cutter, ensuring zero slippage under heavy cutting torque.
Maximum Rigidity for Face Milling: Forged from premium alloy steel (such as 20CrMnTi) and case-hardened to HRC 56-60. The solid, thick-walled construction of the arbor absorbs the heavy interrupted cutting forces generated by large indexable face mills, preventing vibration and chatter.
Precision FMB Pilot: The metric pilot diameter (e.g., 22mm, 27mm, 32mm) and the external NT machine taper are precision-ground simultaneously. We guarantee a maximum Total Indicator Runout (T.I.R.) of ≤ 0.005mm (5 microns), ensuring all inserts on your face mill engage the material evenly for superior surface finishes.
Secure Drive Keys: Integrated, hardened drive keys perfectly match the keyways on standard metric shell mills, transmitting massive cutting torque directly from the spindle to the cutter without relying on friction.
Standard Drawbar Threads: Machined with standard internal threads at the rear of the taper to perfectly match your machine's manual drawbar (e.g., M12 for NT30, M16 for NT40, M24 for NT50). Imperial (inch) drawbar threads are also available upon request.
Includes Locking Screw: Every arbor comes complete with the heavy-duty central locking screw required to secure the face mill to the holder.
Direct Manufacturer Savings: Bypass trading companies and source premium DIN 2080 manual machine tooling directly from our factory for highly competitive wholesale pricing.
Complete Spindle Compatibility: We manufacture the full range of NT tapers: NT30 (for smaller knee mills), NT40 (the most common size for universal milling machines), and NT50 (for heavy-duty boring and milling machines).
Comprehensive FMB Sizes: Available to fit all standard metric face mill bore diameters: FMB16, FMB22, FMB27, FMB32, and FMB40.
Strict Quality Control: Every tool holder undergoes rigorous inspection using 3D CMMs and taper gauges to verify dimensional accuracy and taper angle (AT3 standard) before packaging.
Q1: What does "FMB" mean on a face mill holder?
A: "FMB" designates a metric face mill arbor designed to hold shell mills with metric bore diameters. The number following "FMB" is the exact diameter of the pilot spigot in millimeters. For example, an FMB22 arbor has a 22mm pilot and is designed to hold a face mill with a 22mm center hole.
Q2: How do I choose the correct FMB size for my face mill?
A: You must measure the center bore (hole) diameter of your indexable face mill cutter.
If the bore is 22mm, you need an FMB22 holder.
If the bore is 27mm, you need an FMB27 holder.
If the bore is 32mm, you need an FMB32 holder. Note: If your face mill has an imperial (inch) bore, such as 1" or 1-1/4", you will need an FMA (inch) style arbor, not FMB.
Q3: Can I use an NT40 holder in a BT40 or SK40 CNC machine?
A:No. While NT40, BT40, and SK40 all share the same 7/24 taper angle, the top portion is completely different. NT holders have a cylindrical pilot and an internal thread for a manual drawbar. BT and SK holders have a specific V-flange for an Automatic Tool Changer (ATC) and internal threads designed to accept a pull stud (retention knob). They are not interchangeable.
Q4: Does the holder include the screw to hold the cutter?
A: Yes, all of our NT FMB Face Mill Holders come fully assembled with the central locking screw and the drive keys installed.
Achieve mirror-like finishes and heavy material removal on your manual mills with our DIN 2080 NT FMB Face Mill Holders.
