Metal Amber M35 Full Ground High Speed Steel Twist Drill Bit
Manufactured from M35 steel, with molybdenum and cobalt added to
creates a hardened alloy, measuring Rockwell hardness up to 67 with
5% Cobalt, for much faster cutting and extra longer life span, with
up to twelve times when compared with an average HSS drill bit. No
center punch is needed—the 135° Quick-Cut points are self-centering
and penetrate quickly with less pressure. Will not "walk" or
"wander" Extremely heat resistant; must be used and operated at
1500 RPM or greater for maximum efficiency. Straight shank allows
for firmly holding and accurate centering,
- Ground point drill bits suitable for ferrous and non-ferrous
metals, offering good drilling speeds and extended working life.
- Fast, accurate drilling.
- Application: Steel, Cast iron, Aluminium, Malleable Cast iron,
- M35 drill bit with 135° split point tip and optimised flutes offers
fast drilling speeds in a contractors, low cost option.

hss drill bits metal Application
It is often used in power-saw blades and drill bits. It is superior
to the older high-carbon steel tools used
extensively through the 1940s in that it can withstand higher
temperatures without losing its temper (hardness).
This property allows HSS to cut faster than high carbon steel,
hence the name high-speed steel. At room temperature,
in their generally recommended heat treatment, HSS grades generally
display high hardness (above Rockwell hardness 60) and abrasion
resistance (generally linked to tungsten and vanadium content often
used in HSS) compared with common carbon and tool steels.
