Lollipop Arc Radius Ball Nose End Mill – Coated Tungsten Carbide Extended Shank for Steel & Aluminum

Overview

The Lollipop Arc Radius Ball Nose End Mill combines a reduced‑neck “lollipop” profile with premium tungsten carbide construction and advanced coating to deliver exceptional precision and durability. Designed for both steel and aluminum machining, its straight extended shank and arched ball nose make it ideal for undercutting, contouring, and 3D profiling in CNC milling centers.

Key Features

• Tungsten Carbide Construction:
  Crafted from fine‑grain tungsten steel (carbide) alloy, this end mill offers outstanding hardness (HRC55) and wear resistance for long tool life in demanding metalworking applications.

• Coated for Performance:
  Available with advanced AlTiN or Nano‑bronze coatings to reduce friction, improve heat dissipation, and extend cutting edge longevity at high speeds.

• Lollipop (“T‑Shaped”) Neck Design:
  Features a reduced‐diameter neck above the ball radius that provides clearance for undercutting beneath overhangs and tight internal features.

• Arched Ball Nose Geometry:
  The rounded, smooth‑radius cutting tip enables precise contouring and 3D surface finishing, minimizing tool marks on complex profiles.

• Extended Straight Shank:
  Offers extra reach (overall lengths from 50 mm to 100 mm) for deep pocket and recessed feature machining with minimal deflection.

• Four‑Flute Design:
  The 4‑flute configuration balances cutting forces and improves surface finish in both ferrous and non‑ferrous materials.

• Versatile Diameter & Radius Options:
  Available in neck radii from R0.75 mm up to R6 mm and cutting diameters from 3 mm to 20 mm to suit a wide range of applications.

• Precision Ground for Low Run‑Out:
  Ground to tight tolerances for minimal vibration and high‐accuracy machining.
