Description
The Palbit HiFeed SO10-08 D.750-W.750/8.00-02-08 is a long-reach high-feed end mill engineered for performance and rigidity in extended milling applications.
With its ¾-inch cutting diameter, 8-inch overall length, and 2-insert Weldon shank design, this cutter delivers stable, precise results in deep-pocket, cavity, and mold machining — all while maintaining Palbit’s signature high-feed performance.
Designed for high-speed roughing at shallow depths, the SO10-08 geometry combines a 10° lead angle with a +2° rake to ensure smooth chip evacuation, reduced cutting forces, and longer tool life even under aggressive conditions.
Key Features
- Long-Reach 8" Design: Ideal for deep cavities and hard-to-reach features.
- High-Feed Geometry (10° lead angle): Enables fast feed rates and minimal tool deflection.
- Secure ¾" Weldon Shank: Prevents tool pullout and ensures rigidity.
- 2-Insert Configuration: Balanced for stability and reduced chatter at long projection lengths.
- Optimized for SO…0803 Inserts: Compatible with Palbit’s proven high-feed insert family for versatile performance across materials.
Q1: What’s the difference between this tool and PN 181078700?
A: Both have the same ¾” diameter and 2-insert layout, but this model (181078800) features a longer 8-inch body for extended reach in deep cavities or when extra projection is required.
Q2: Is the 8" length stable for high-feed milling?
A: Yes, provided you use a rigid setup and proper holder support. The Weldon shank prevents pullout, and Palbit’s geometry minimizes vibration even at long projection lengths.
Q3: What materials can it machine effectively?
A: The cutter performs exceptionally well on carbon steels, stainless steels, cast irons, and pre-hardened tool steels up to about 45 HRC. It’s a versatile choice for mold shops and aerospace machining.
Q4: What kind of operations is it intended for?
A: Primarily high-feed roughing, deep pocket machining, and contour milling where traditional short tools can’t reach. It’s not meant for finishing passes.
Q5: What insert should I use?
A: It accepts Palbit SO…0803 inserts, the same family used across the SO10-08 line, ensuring consistency in inventory and predictable wear performance.
Q6: How deep can I cut with it?
A: The maximum depth of cut (Ap max) is 0.69 inches, but it’s optimized for high-feed passes at shallower depths (0.03"–0.06") with higher feed per tooth for maximum efficiency.
Q7: Is tool pullout a concern at this length?
A: Not typically — the Weldon shank provides a secure mechanical lock in the toolholder, which is ideal for high-feed applications with extended reach.
Q8: How many inserts does it use?
A: Two inserts, which simplify indexing and reduce consumable costs while maintaining cutting balance.
Q9: What kind of surface finish can I expect?
A: While it’s primarily a roughing tool, the positive rake geometry allows it to leave a cleaner surface than most roughing cutters, often reducing the need for heavy finishing operations.
Q10: Can it be used on smaller CNC machines?
A: Yes — the compact ¾” diameter makes it suitable for CAT40 and BT40 spindle machines. Just ensure proper support and shorter gauge length when possible for optimal performance.
Q11: Are inserts interchangeable with other Palbit HiFeed cutters?
A: Yes — it shares the SO…0803 insert platform with other SO10-08 models, simplifying tool crib management and reducing stock complexity.
Q12: Is it available in shorter or larger diameters?
A: Yes. Palbit offers additional ¾", 1", and 1.25" Weldon shank models in various lengths (5", 6", 8"), as well as arbor-mount versions up to 2.00" diameter.
Q13: Is this tool factory-balanced?
A: Yes, all Palbit HiFeed cutters are precision-balanced for standard spindle speeds (up to 12,000–15,000 RPM). For higher-speed or precision mold applications, dynamic balancing can be performed.
