1-1/2″ HSS 4MT Cobalt Steel Taper Shank Drill Bit Technical Specifications
Cobalt taper shank drills are made of heat resistant M35 5% cobalt
Engineered with heavy-duty construction to perform well in tough, hard-to-machine materials
Notched point
135° split point tip for fast penetration and accurate drilling
For use in hard materials such as inconel, stainless steel and titanium
Display high red hardness, permitting speeds up to 30% greater than with conventional M2 high speed
A taper shank drill (high-speed steel) is a cutting tool that is attached to a drill press, a milling machine, a lathe, etc. and used to drill holes. The base metal, high-speed steel is a material with metal components such as tungsten, molybdenum, and chrome added, and has excellent abrasion resistance and toughness.
Taper-shank drill bits are directly inserted into the spindle, driving sleeve, or socket of a machine such as a drill press or lathe.
This saves time when installing and changing out bits on the machine compared to other styles of drill bits.
Taper-shank drill bits are self-locking, which means the friction between the bits and the tool holder keeps the bits in place, even in high-torque applications.
These bits should not be used in a collet or chuck.
1,Precise dimension,long life and high efficiency.
2,High-speed steel (HSS) provides hardness for wear resistance Black Oxide HSS4241 Taper Shank Drill Bits For Alloy Brass Aluminum Iron
3,Bright finish increases chip flow in softer materials such as aluminum, wood and plastic
4,Self-centering 118-degree notched point penetrates material without a pilot hole more easily than a conventional point, and maintains a sharp cutting edge
5,Morse taper shank allows the tool to be inserted directly into the machine’s spindle to facilitate high-torque applications such as large cut diameters HSS Taper Shank Twist Drilling Bits Extra Long For Metal
6,When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
7,Designed to perform in a broad range of materials in the iron and steel families
8,Spiral flutes are constructed with a higher flute angle to remove chips more easily. HSS 4241 Taper Shank Twist Drill Bits For Metal Alloy Copper
Taper-shank drill bits press fit into a Morse-taper shank usually found on drill presses and lathes. They’re used in heavy-duty and horizontal drilling. The taper provides a strong, slip-resistant grip in heavy, high-torque applications. Fully Ground HSS M2 Morse Taper Shank Drill Bits For Stainless Steel
High-Speed Steel Taper-Shank Drill Bits
These high-speed steel taper-shank drill bits for metal and plastic absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. Regular-spiral flutes are best suited for nonchipping hard materials such as nonferrous metals, cast iron, and structural steel.

Straight Shank — Chuck Grip
A straight shank drill has a perfectly cylindrical shank ground to h8 tolerance (for fully ground drills) or h10 tolerance (for rolled drills). The shank diameter equals the drill diameter for sizes up to 13 mm. Above 13 mm, the shank is often reduced to 13 mm (called a reduced shank or blacksmith drill) to fit standard chucks.
The 3-jaw chuck applies radial clamping force from three equidistant jaws. Torque is transmitted entirely through friction between the jaws and the shank surface. This means: HSS Cobalt 5% M35 DIN345 Taper Shank Drill Bits
