CNC Grooving Tool Holder, SPB Parting Block Adapter, Alloy Steel Cut Off Block, High Grinding, For SMBB1626 2026 2032 2532 3232(SMBB2026)

Features:* Adopting for grinding technology, the repeat positioning accuracy is ≤0.005mm, the stability of the processing process and the for surface finish of the workpiece.* Adapting to BT/HSK/CAT toolholder system (configured by model), supporting φ16-26mm tool installation, covering milling cutters, drills, boring cutters and other types of CNC tools.* The tool holder body is made of alloy steel quenching treatment, with internal reinforcement rib design, vibration resistance is improved by 30%, suitable for heavy cutting and high conditions.* Integrated internal cooling channel (optional), directly delivering coolant to the tool tip, reducing cutting temperature, extending tool life and improving processing efficiency.* Equipped with hydraulic or mechanical locking mechanism (depending on model), tool change time is ≤3 seconds, compatible with mainstream CNC machine tool automatic tool changer (ATC).* The key for surface is nitrided and hardened, with a hardness of HRC60 or above, wear resistance is improved by 50%, and maintenance frequency is reduced.Specifications:Part Name: CNC Tool HolderModel: SMBB1626, SMBB2026, SMBB2032, SMBB2532, SMBB3232 (optional)Material: Alloy SteelColor: BlackSize: As shownApplicable Blade Details: (as below)SMBB1626, 16mm, for SPB 26-*;SMBB2026, 20mm, for SPB 26-*;SMBB2032, 20mm, for SPB 32-*;SMBB2532, 25mm, for SPB 32-*;SMBB3232, 32mm, for SPB 32-*.Package Contents:1 x CNC Tool Holder (without blade)1 x WrenchNote:1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.2.Please allow slight manual measurement deviation for the data.

• [KIT DETAILS & COMPATIBILITY] This package contains CNC tool holder and wrench; blades are not part of the package. Select SMBB1626, SMBB2026, SMBB2032, SMBB2532 or SMBB3232 to match your cutter diameter and BT/HSK/CAT toolholder interface.
• [ACCUREPEAT POSITIONING] Designed for a repeat positioning accuracy near mm, the holder stabilizes the cutting process to help achieve consistent part tolerances and superior finish for ACROSS milling, drilling and boring operations.
• [ENGINEERED FOR STABILITY] Alloy steel quench treatment plus an internal rib design increases stiffness and reduces vibration by roughly 30%, supporting reliable cutting under high and heavy load conditions.
• [COOLANT DELIVERY & ATC READY] Optional internal coolant channel supplies fluid directly to the cutting z to reduce heat buildup and prolong tool life. Built-in hydraulic or mechanical lock supports automatic tool changers and sub-3 second tool swaps.
• [DURABILITY & SIZE CHECK] Nitrided contact areas reach 60 or higher to cut wear and lower maintenance intervals. Always verify the SIZE CHART to pick the correct model and blade size instead of using size charts.
