SPADE DRILL TIP MATERIAL INFORMATION
Steel
Rex M-4* or AISI M-4 is a special purpose high speed steel
designed to give high wear resistance in tools. Its high vanadium and carbon content
provide for superior resistance to cratering and wear in cutting applications involving
high speed and light cuts. It is designed to give maximum performance working with
abrasive materials exhibiting excellent wear resistance.
CPM Rex T15* or AISI T15 is a super high speed steel made
by the Crucible Particle Metallurgy (CPM) process. It is a tungsten type high speed
steel containing high vanadium for excellent abrasion resistance, and cobalt for
good red hardness. CPM Rex T15 is ideal for cutting difficult to machine materials
where high frictional heating is encountered.
CPM Rex 76* or AISI M48 is a super high speed steel made
by the Crucible Particle Metallurgy (CPM) process. It has high carbon, vanadium and
cobalt for abrasion resistance comparable to T15 and superior red hardness. Its high
hardness, fine grain size and uniform carbide distribution make it outstanding for
special purpose cutting tools. The best applications are where high red hardness,
high abrasion resistance, and good toughness can be used to advantage.

Carbide
C-2 (K20) Carbide is medium fine grain carbide for general purpose machining,
Cast Iron high temperature alloys, and Non-Ferrous metals.
C-3 (KO) Carbide is fine grain carbide used for light finishing in Cast Iron
and Non-Ferrous metals.
C-5 (P-40) Carbide is medium grain carbide used for rough cutting or drilling
of steel and steel castings.
Wear Resistance - Tungsten carbide wears up to 100 times longer than steel
in conditions including abrasion, erosion and galling. Wear resistance of tungsten
carbide is better than that of wear-resistance tool steels.
SPADE DRILL TIP COATING INFORMATION
Available Coatings
TiN (Titanium Nitride) A general-purpose coating for iron
based materials that will give good abrasive and adhesive protection for cutting
tools at moderate speeds and feeds.
TiCN (Titanium Carbonitride) A high performance coating
for high speed machining that is tougher than TiN and harder for more wear protection
and higher speeds and feeds, but should not be used with coolant.
TiALN (Titanium Aluminum Nitride) A high performance layered
coating for high speed machining that can be wet, semi-dry or dry. Excellent for
cast iron, stainless steel, nickel based and titanium based alloys.
TiALN + (WC/C over TiALN) A composite coating designed
primarily for chip evacuation of soft gummy materials, but also can be helpful to
reduce friction in the machining of alloys that tend to work harden. Very good resistance
to adhesive wear (built up edge).
Also Available are some new TiALN Coatings
TiALN Extreme - for hardened tool and mold steels (Rc
50 and higher) D-2, H-15, M-2, P20 ext.
TiALN Exceed - for super alloys in the medical, nuclear
and aerospace industries. Titanium and titanium alloys, high nickel and high chrome
alloys, Inconel, Monel, etc.
TiALN Endura - a thicker coating (8 - 10 microns) for
rough machining operations on honed cutting edges.
