Description
The Palbit HiFeed SO10-08 D1.00-W1.00/8.00-03-08 is a long-reach high-feed end mill designed for deep cavity machining, pocket roughing, and mold work that requires extended projection and superior rigidity.
With its 1-inch diameter, 8-inch body length, and 3-insert layout, this tool delivers excellent balance between reach and cutting performance — ensuring high productivity even in difficult-to-access areas.
Built with positive rake geometry (+2°) and a 10° lead angle, the cutter provides smooth chip evacuation, reduced cutting forces, and a consistent surface finish across steels, stainless steels, and high-temp alloys.
Its Weldon shank design offers a secure mechanical grip, preventing tool pullout under aggressive feeds and heavy cutting conditions.
Key Features
- 8" Long-Reach Design: Access deep cavities and complex mold geometries with minimal deflection.
- High-Feed Geometry (10° Lead Angle): Enables shallow cuts at high feed rates for maximum metal removal.
- Three-Insert Configuration: Ensures balanced load distribution and stable performance under high feeds.
- 1" Weldon Shank: Provides rigid clamping and prevents slippage.
- Compatible with SO…0803 Inserts: Standardized across the SO10-08 family for consistent performance and easy inventory management.
Q1: What makes this cutter suitable for long-reach operations?
A: Its 8-inch overall length and rigid Weldon shank make it ideal for deep cavities or tall workpieces where shorter tools can’t reach. The high-feed geometry maintains stability even under long projection.
Q2: What materials can it cut effectively?
A: It performs exceptionally well on carbon steels, tool steels, stainless steels, and cast irons. With the correct insert grade, it also handles pre-hardened materials up to ~45 HRC.
Q3: What insert does it use?
A: It uses the Palbit SO…0803 insert, common across the SO10-08 line, simplifying inventory and allowing easy interchangeability between cutter sizes.
Q4: What is the maximum depth of cut (Ap)?
A: The maximum depth of cut is 1.26 inches, but best performance is achieved with shallow passes and high feed-per-tooth values, typical of high-feed machining.
Q5: Is it stable at full reach?
A: Yes — the 3-insert configuration maintains balance, and the positive geometry minimizes cutting forces. For maximum performance, use rigid toolholders and shortest possible overhang.
Q6: Can I use it for finishing?
A: It’s designed primarily for roughing, but the clean chip flow and positive rake geometry produce a good surface finish, reducing secondary finishing requirements.
Q7: What spindle setups is it compatible with?
A: Fits most CAT40, BT40, and HSK63 toolholders with 1” Weldon shank capability. Works best on vertical and horizontal CNC machining centers.
Q8: How many inserts does it use?
A: The cutter holds three inserts, evenly spaced for balance and load distribution during heavy cutting.
Q9: How does this compare to the shorter 181078900 model?
A: This version offers the same 1” diameter and insert configuration, but with an extended 8-inch reach, ideal for deeper cavities or part features that shorter cutters can’t access.
Q10: Is tool pullout a concern at this length?
A: No — the Weldon shank design provides a mechanical flat that locks securely into the holder, preventing pullout during aggressive feeds.
Q11: Are inserts interchangeable with other Palbit HiFeed tools?
A: Yes. The SO…0803 insert platform is shared across the entire SO10-08 series, which includes diameters from ¾” to 2.00”, simplifying tool crib management.
Q12: What balancing is required?
A: All Palbit HiFeed cutters are factory balanced for spindle speeds up to 12,000–15,000 RPM. For high-precision mold work or higher speeds, optional dynamic balancing can be used.
Q13: What’s the ideal chip load and speed range?
A:
- Feed per tooth (fz): 0.015"–0.030"
- Cutting speed (Vc): 400–850 SFM for steels, 200–450 SFM for stainless, 350–600 SFM for cast iron
- Adjust feeds and speeds based on rigidity and insert grade.
Q14: Is this a stock item?
A: Yes — Palbit lists the SO10 D1.00-W1.00/8.00-03-08 as a stock item, available through authorized distributors and partners.
