T075X Economy General-Purpose Advanced End Mill

Economy general-purpose advanced series, benchmarked against top domestic brands

The T075X is an economy end mill that doesn't cut corners on the basics. It uses unequal flute spacing and an unequal helix to keep vibration down—especially useful when you're running long passes or working in corners. Chip evacuation is handled by a specially formed groove, so you're not stopping to clear birdsnests.

It handles dynamic (trochoidal) milling, plunge milling, and side milling without complaint. You can run it from roughing through to finishing and still get a respectable surface finish. Materials? Ordinary steel and alloy steel up to 40HRC, quenched and tempered steels like PX and NAK up to 45HRC, high-hardness SKD and DAC up to 55HRC, stainless like SUS303/304 up to 35HRC, plus cast iron and aluminum. Sizes run from φ1 to 20mm in square, corner radius, and ball nose types.

Highlights
Key Advantages
  • Unequal flute spacing and unequal helix work together to damp vibration—noticeable when you're milling deep pockets or thin walls.
  • The formed groove design moves chips out fast, which means fewer interruptions and less chance of recutting.
  • One tool for three operations: dynamic milling, plunge milling, and side milling. You don't need to swap tools as often.
  • Stable cutting from roughing to finishing—users report good surface finish without changing speeds and feeds mid-job.
  • Priced as an economy series but tested against top domestic brands, so you're not sacrificing reliability for cost.
  • Square φ1-20mm, corner radius φ1-12mm, ball nose R0.5-R6mm. Covers most general-purpose milling needs.
Use Cases
Applications
  • Mold machining—especially on PX, NAK, HPM, and STAVAX steels where stable cutting and surface finish matter.
  • Medical component production—small parts that need precise, vibration-free cuts.
  • Automotive parts milling—production runs where tool changes eat into cycle time.
  • New energy sector—battery and powertrain components that require consistent finishes.
  • 3C electronics—small precision parts where chip evacuation can make or break the job.
  • Aerospace and construction machinery—general milling where you need a dependable, everyday tool.

FAQ
FAQ
What materials can the T075X end mill handle?
It's rated for ordinary steel and alloy steel up to 40HRC, quenched and tempered steels (PX, NAK, HPM, STAVAX) up to 45HRC, high-hardness steels like SKD and DAC up to 55HRC, stainless steel (SUS303, SUS304) up to 35HRC, plus cast iron and aluminum alloy. If you're pushing harder materials, just watch your feeds and speeds.
What milling operations does the T075X support?
Dynamic (trochoidal) milling, plunge milling, and side milling. It's stable enough to run from roughing through finishing without switching tools, which is handy when you want to keep setups simple.
What is the specification range of the T075X series?
Square type goes from φ1 to 20mm. Corner radius type runs φ1 to 12mm. Ball nose type covers R0.5 to R6mm. If you need something outside these ranges, ask—custom sizes may be possible depending on quantity.
How does the unequal flute spacing benefit machining?
Unequal flute spacing and unequal helix break up the rhythm of the cut, which cuts down on vibration. Less vibration means smoother cutting, better surface finish, and longer tool life—especially in corners or when milling thin walls.
What is the typical lead time for T075X orders?
Standard sizes are usually in stock and ship quickly. For larger quantities or custom specs, lead time is typically 2–4 weeks depending on order volume. We'll confirm at the time of quote.
Is the T075X suitable for mold machining?
Yes—it's built with mold machining in mind. Users run it on PX, NAK, HPM, and STAVAX and report stable cutting and good surface finishes. The vibration damping helps in deep cavities and fine details.
