The ancient 500 combines a deep radial flute with a 118 split point on the cobalt base. Applicable to stainless steel and alloy steel; Valley 500 can also effectively drill aluminum and soft steel. Available tin coating and bright finished products as standard inventory items.
High temperature alloy
The Ti series of the cobalt drill is well suited for hard working applications, which is a reliable tool. Ti drill is a kind of M35 cobalt, 135 split point drill with a heavy network design. Available bright finished products, tin and fire, applied to hardened steel, stainless steel and nickel alloys.
Nc point – start drill
The nc point drill is a high-precision drill, designed to create precise hole position for secondary drilling operation. The numerical control point drill should not be interstitial and not designed for the depth of the drill point. The 90 and 120 bit drills are mainly used to set up an initial position for the initial position of the second bit of 118135.
Microdrill – small diameter cobalt
The high – ring cobalt micro drill is manufactured with high precision and strict tolerance, requiring small diameter holes to be applied to 0.05 mm (0.002 in). Both of these micro drills have the right and left helical structures, which are generally 1.0, 1.5, or 2.0 millimeters in diameter, depending on the diameter of the drill. This increases the fixed hardness and increased surface area.
N- standard spiral
The n-type is the flute design of the drill. The N HSS/HSCO rig is a universal design that provides advice for the economic drilling of various materials. The company provides N HSS/HSCO drilling RIGS, stubs, working positions and additional length of inventory, bright paint or tin plating.
W – high spiral
A w-type drill is a type of flute with a high helical or fast helical type, in the process of the evacuation of the chip. High helical drilling is best used for applications of aluminum and soft steel, and chip packaging can be a problem. In many applications, the w-type rig was replaced by the GT100 parabolic drill
H – Low Helix
H type bit is a long flute form with low or slow spiral. This kind of slow spiral is the most suitable for horizontal drilling application, improving the evacuation speed of the chip. This style of tool is very popular in the application of the screw machine. The slow spiral also reduces the cutting edge of the hard material. Get the stub from the stock and the length of the work.
Taper Shank – Morse Taper Shank
Morse taper shank drill adopts a standard taper shank design for taper drill clamp. Morse Taper was invented in the mid-1819 by Stephen a Morse (who was also the inventor of the twist drill). Morse’s size is 8, between 0 and 7. Usually this is abbreviated to MT and then a number. For example, Morse’s number 4 is MT4. The taper of the MT2 is the capacity of up to one half of the drill pressure.
