Description
The Palbit HiFeed SO10-08 D.750-W.750/5.00-02-08 is a precision-engineered high-feed end mill designed for rapid material removal in smaller-scale machining operations. With its ¾” cutting diameter and Weldon shank design, this tool offers excellent rigidity and balance — perfect for vertical machining centers, toolroom setups, and applications requiring tight tolerances in confined spaces.
Equipped with two SO…0803 inserts and a 10° lead angle, it allows high feed-per-tooth rates while maintaining a smooth cutting action and superior surface finish. Ideal for roughing steels, stainless steels, and cast materials where shorter cycle times and tool life optimization are essential.
Key Features
- Compact ¾” Diameter: Perfect for smaller parts and high-feed pocket milling.
- Weldon Shank Design: Provides secure, anti-pullout grip for rigid performance.
- 2-Insert Configuration: Ideal balance of feed rate and stability in tight areas.
- Positive Geometry (+2° rake / +2° pitch): Low cutting forces and reduced vibration.
- High-Feed Performance: Enables aggressive feeds at shallow depths with consistent chip evacuation.
Q1: What makes this cutter different from a standard end mill?
A: Unlike a traditional end mill, the SO10-08 uses a high-feed geometry (10° lead angle) to remove material faster with less cutting resistance — perfect for roughing at high speeds and shallow depths.
Q2: Can I use this in a standard CAT40 or BT40 spindle?
A: Yes. The ¾” Weldon shank is compatible with most CAT40, BT40, and HSK holders designed for end mills. Always ensure your holder has Weldon flats for maximum grip.
Q3: What materials can it cut?
A: Optimized for carbon steel, stainless steel, tool steel, and cast iron. It performs exceptionally well on materials up to ~45 HRC with the correct insert grade.
Q4: What insert does it take?
A: The tool uses Palbit SO…0803 inserts, part of the SO10-08 family, designed for high-feed milling and long tool life.
Q5: How deep can it cut?
A: The maximum depth of cut (Ap max) is 0.79 inches, but best performance is achieved at shallower passes (0.03"–0.06") with higher feed per tooth.
Q6: What kind of operation is it best suited for?
A: It’s ideal for pocketing, ramping, and 3D contour roughing — especially in smaller molds or die inserts where space is limited.
Q7: Is this more for roughing or finishing?
A: Primarily roughing, but due to its positive rake geometry, it leaves a relatively smooth finish that often reduces the need for secondary operations.
Q8: How many inserts does it use?
A: Two — which keeps inventory simple and cost per edge low.
Q9: Are inserts easy to index or replace?
A: Yes. The open pocket design allows quick insert changes without removing the tool from the holder — minimizing downtime.
Q10: Is balancing required before use?
A: Not typically. The cutter is factory-balanced for standard spindle speeds up to 12,000–15,000 RPM. For ultra-high-speed machining, optional dynamic balancing can further improve precision.
Q11: What is the recommended chip load?
A: Typical chip loads range from 0.010–0.025 in/tooth, depending on material hardness and setup rigidity. Palbit provides cutting data charts by material and insert grade.
Q12: Is it available in other lengths or diameters?
A: Yes — the SO10-08 Weldon shank line includes cutters from ¾” to 1.25” in diameter and various lengths (5–8 in).
