This work of art is so much more than just a lighting fixture.75" Wide Black / Polished Chrome Linear Pendant The edge of each slender band encases a small LED strip covered by a frosted lens.Gyro II 6-Light 13..

With an added touch of elegance, the clean simple orb frame falls graciously from the ceiling on a gently swirling lifeline.

Hand taps are popular for use in general machine tapping or CNC tapping..

Heavy Duty 135 Split Point, Cobalt Steel, Jobber Length, manufactured to National Aerospace standard 907. X Cobalt Heavy Duty Jobber Length Drill Bit Sizes smaller than 1/16” or #52, and larger than 1/2” have the 118° standard point. The 135 split point is self-centering and reduces thrust.

Adjustment is obtained by a fine pitch screw which forces the sides of the die apart, or allows them to spring together.For threading, a High Speed Steel Round Adjustable Die is desired for improved wear life. 1-5/8"-12x3" OD HSS Round Adjustable Die Special The slot is beveled so that when the dies are used in a machine holder the adjusting screw can be removed and adjustment made by the adjusting screws in the holder.

These drills are jobberstandard length have a 135 degree split point tip and a 3 -flat shank to prevent spinning.25/64in Stepped Point Cobalt Drill Bit with 3-Flat Shank Product Specs: Size: 25/64, Material: Cobalt, Finish: Gold, Flute Length: 4-3/16, Overall Length: 5-5/8, Shank Type: 3-Flat, Style: Jobber, Cutting Angle: 135, Point Type: Stepped, Number of Flutes: 2, Cutting Direction: Right Hand, Decimal Equivalent: 0.50874mm They can be used to enlarge existing holes or to create new, smoother holes in a wide range of materials such as acrylics, steel, metal, brass and other hard metals.4531, Metric Equivalent: 11.

If the counterbored portion is shallow (1/8" or less), the operations is usually known as spot-facing; for example, a flat seat for a bolt head or nut.. If, on the other hand, the hole is enlarged to a considerable depth, it is designated as counterboring.1-1/2"x3/8" Pilot Hole HSS Taper Shank Counterbore These counterbores are made of two-piece construction, having an integral shank and counterbore-cutter, and a pilot that is interchangable, which provides flexibility in the use of the tool.

They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow.. The 135 degree split point is self-centering and reduces thrust.
