AMG’s R4.5*4°-D16-110-4T carbide taper end mill is specifically
engineered for precision slope and curved surface machining on
automation equipment parts. Made with HF25 ultra-fine grain carbide
substrate, this tool offers outstanding wear resistance and
anti-chipping performance, keep stability even under high-load
machining conditions. Featuring 4° taper design and R4.5 ball nose
transition, with 16mm cutting diameter, 110mm total length, and 4
distributed flutes, it ensures balanced cutting forces, reduced
vibration, smooth chip evacuation, and high-quality surface finish.
It is particularly suitable for mold slope finishing, deep cavity
taper machining, and high-precision curved surface milling in
automated equipment parts.
Applications
Widely used for slope, curved surface, and deep cavity taper
machining on automation equipment components, molds, medical parts,
and automotive parts. It is ideal for materials including steel,
cast iron, stainless steel, aluminum alloys, and titanium alloys,
making it an excellent choice for precision mold making and
automation structural components.

Working Principle
This taper end mill use 4° taper to provide greater chip evacuation
space and reduce interference risks during deep cavity and curved
surface machining, enhancing machining efficiency. The R4.5 ball
nose reduces cutting impact and prevents visible tool marks on the
workpiece, improving surface finish. The 4-flute design ensures
even force distribution during slope and curved surface cutting,
allowing for high-speed, high-feed machining while maintaining
stability.

FAQ
Q1: Is there a risk of tool breakage when machining slopes and
curves with taper end mills?
We recommend step machining with stable clamping systems, which
effectively prevents tool breakage. Using coated models further
increases durability.
Q2: Can it be used for stainless steel and titanium alloy
machining?
Yes, it is fully compatible. We recommend using coated for better
performance on these materials.
Q3: How to select the correct taper end mill specification?
Please choose based on your part’s taper angle, cutting depth, and
surface radius requirements. If you are not sure, you can send your
drawings to AMG’s technical team for assistance.
