1. Drilling. MCC Drill : A 90°point angle is used to reduce thrust when drilling, this prevents delamination and also improves hole tolerance. MCA Drill : A unique flute design is employed to prevent the aluminium chips from damaging the finish of the CFRP section thus reducing the gap in hole size between the aluminium and CFRP section. 1.

Figure 7 shows the tool wear of the end mill after about 0, 10, and 20 hours passed in real gear machining. The length of tool wear of the cutting edge was about 34 μm. Since the radial relief angle of end mill is 11 degree, the diminution Δr of radius of end mill is 34 μm * tan 11 deg. = 6.6 μm after about 10 hours passed.

A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable.
These parameters for the "P" Mild Steel Material Group are ONLY for < 18-20 HRc (,223 - 217 Brinell Hardness). Our Raptor DVH, Raptor 3/6, and Python series end mills are better suited for the "P" Mild Steel Material group, but in a pinch the Viper's work very good here.
