Twist Drills -
drills that use a cutting point and helical flutes to make a hole.
---------------------------------------------------TWIST DRILL LENGTHS---------------------------------------------------
Jobber Length -
The standard drill bit length for most drilling applications.
Mechanic Length -
A shorter drill bit length with flats on the shank to provide more stability for harder drilling process.
Screw Machine Length -
The shortest drill bit length for a lower chance of breakage, used mainly in machine driven drilling processes.
---------------------------------------------TWIST DRILL MATERIAL TYPES---------------------------------------------
CN-TECH -
Cryogenic treatment creates a more uniform “grain” structure by transforming retained austenite into martensite.
Magnum Super Premium -
Made with special Hi-Molybdenum tool steel. Body and clearance are gold surface treated for maximum lubricity.
M42 Cobalt -
Manufactured from M42 HSS containing 8% cobalt which increases high red hardness.
Silver and Deming -
These drill bits have straight shanks smaller than the diameter of the bit. Another name is the Reduced-Shank drill bit.
---------------------------------------------SILVER AND DEMING LENGTHS-----------------------------------------------
Jobber Length -
drill bits have straight shanks smaller than the diameter of the bit. Another name is the Reduced-Shank drill bit. Generally, this bit is 6 inches long and consists of a 1/2-inch shank with a 3-flats on shank.
---------------------------------------SILVER AND DEMING MATERIAL TYPES-----------------------------------------
Magnum Super Premium -
Made with special Hi-Molybdenum tool steel. Body and clearance are gold surface treated for maximum lubricity.
M42 Cobalt -
High red hot hardness of cobalt steel permits speeds 30% higher than regular high speed steel drills.
General Purpose -
High-speed steel recommended for use in drilling equipment with 1/2" chucks.
Taps and Dies -
tools used in the threading process to create screw threads.
------------------------------------------------------------TAP TYPES-----------------------------------------------------------
Tapering Taps -
Taps with 8-10 threads tapered on the point for easy thread starting in tough materials.
Plug Taps -
Taps with 3-5 threads tapered on the point for general use when tapping into the bottom of the hole is not critical.
(This is the most widely used style.)
Bottoming Taps -
Taps with 1-2 threads tapered on the point. Made for use after threads have been started for tapping to the bottom of a hole.
Spiral Point -
Designed for machine tapping through holes in a wide variety of materials. The point of the tap continuously ejects the chips ahead of the tap, eliminating chip disposal problems and thread damage.
Straight flute -
The most common type of tap. Can be used by hand or for tapping under power. Made for use in general machine tapping or CNC tapping applications. Can be used for through hole or blind hole tapping.
Pipe tap -
Regular Thread tapered pipe taps are used for tapping pipe fittings and couplings in a wide variety of materials.
--------------------------------------------------------TAP MATERIALS--------------------------------------------------------
Hi-Carbon -
Super tough carbon steel, ideal for hand tapping or re-threading
Gold Oxide -
Low temperature stress relief
that enhances lubricity, reduces friction and
increases tap toughness.
Bright Finish -
A general purpose material recommended for non-ferrous metals, wood, and plastics.
------------------------------------------------------------DIE TYPES------------------------------------------------------------
Adjustable Round -
These dies have a recessed adjusting screw so threads can be cut slightly under-size or oversize.
Hex -
Hex shape allows them to be driven in cramped quarters with a wrench.
--------------------------------------------------------DIE MATERIALS---------------------------------------------------------
Hi-Carbon -
High quality carbon tool steel to meet the highest industry standards.
Reamers -
A type of rotary cutting tool used in metalworking, used to enlarge the size of a previously formed hole.
--------------------------------------------------------REAMER TYPES--------------------------------------------------------
Standard Flute -
These reamers are especially designed for the reaming of structural steel plates commonly found in truck frames, rail cars, bridges, and pressure vessels.
Fast Spiral -
The fast spiral reamer, is the more aggressive of the two common styles. It also will fit the needs of users who prefer a stop collar.
Hex Nut -
Designed for aligning and enlarging holes in structural steel applications.
Hole Hog -
This tool is designed exclusively for enlarging existing holes. The 4-flute design eliminates the catching and hogging-in experienced with standard S & D drills when breaking through thinner materials such as truck frames.
Step -
Accurately starts, enlarges and deburrs holes in materials up to 1/2" thick. The 90° notch point starts holes easily. Each reamer has five hole-enlargement steps.
----------------------------------------------------REAMER MATERIALS-----------------------------------------------------
Magnum Super Premium -
Special Hi-Tungsten tool steel, gold surface treated body and clearance for maximum lubricity.
