Carbide Tipped 
Carbide tipping is used to hold a long-lasting edge on tools by brazing a piece of tungsten carbide metal to the edge or end of a steel tool. Saw teeth and drill pits are examples of carbide tipping. 

Carbide Tipped Saw Blade 
Also referred to as a tipped tooth blade, this circular saw blade has carbide tips that are a bit wider than the thickness of the blade, which allows the teeth to cut freely without having the blade bind. 

Carboloy 
Carbon and hard tungsten compound which is used for making cutting blades and saw teeth and as the abrasive on sandpaper. 

Carbon
In its pure form carbon exists as a diamond or graphite; atomic number 6; atomic weight 12.011; atomic symbol C. This element combines with other elements. 

Carbon Arc Cutting (CAC) 
Metal cutting using the heat of an electric arc between the base metal and a carbon electrode. 

Carbon Arc Welding (CAW) 
Welding process, which employs an electric arc from a carbon electrode to the work as the heat source, with or without the addition of filler metal. 

Carbon Arc Welding, Shielded (CAW-S) 
Welding process that uses a carbon electrode shielded with a blanket of flux on the work or the combustion of a solid material or both. 

Carbon Arc Welding, Twin (CAW-T) 
Electric arc welding using an arc between two carbon electrodes as the heat source without shielding and with or without pressure and/or filler metal. 

Carbon Electrode 
Carbon in the form of a rod used as an electrode. 

Carborundum 
Trade name of an abrasive composed of alumina, silicon carbide, etc. 

Carborundum Cloth
Cloth fabric which is used for smoothing that is embedded with Carborundum-like abrasives. 

Carborundum Finish Limestone 
Used in construction where a smooth finish is required, this limestone has a finely ground surface. 

Carborundum Stone 
Manufactured abrasive stone, which uses carbon-silicon abrasives in its formulation. 

Carboy 
Large glass bottle enclosed for protection in a special container or wooden crate; often used as a container for corrosive liquids. 

Carburize 
Also called case hardening. The addition of hardness to the surface of steel by heating the steel in contact with carbon. Heated material is exposed to carbon then hardened by quenching or cooling slowly, reheating and quenching again. Used on tolls which need to retain the resilience of a soft metal to avoid cracking but need a hard surface or when it is simpler or cheaper to shape and carburize a softer material rather than using a harder metal. Cutting tools used for metal lathes or milling machines or the center of a lathe tailstock are usually carburized for wear resistance. Tools that must remain sharp while being resistant to impact are often carburized 

Carcinogen 
Cancer causing substance. 

Carnauba 
One of the primary ingredients of paste wax, which is often used on wood floors, this hard wax comes from the leaves of the wax palm plant. 

Carpenter 
Workman who builds and repairs wooden structures. 

Carpenter's Pencil 
Used for marking measurements on wood, this flat pencil has wide and durable lead. 

Carpenter's Square
Flat L-shaped measuring tool, also called a framing square, is used to calculate lengths and lay out angles. The legs of the L, which come together at a right angle, have measuring tables and marks for rafter cuts etched into them. Also called a framing square.

Carpentry 
The work and trade of building and repairing wooden structures. 

Carpet 
Soft synthetic or natural fiber floor covering. 

Carpet Flange 
Decorative trim piece that is used around an electrical box that is flush into the floor. 

Carpet Pan 
Extension in an underfloor raceway, which is designed to bring an electrical junction box cover level with the carpet or other flooring. 

Carport 
The roof that covers a parking area, normally next to a house. 

Carriage 
Slanting board on a staircase that treads and risers are let into. 

Carriage Bolt 
Bolt with a squarish section under a rounded head without a slot; underneath the head is a square shoulder. It bears a resemblance to a wood screw and is good for wood to wood connections. Carriage bolts have either cut or rolled threads. Cut thread bolts have threads cut into the bolt; the rolled thread bolts have the threads pressed into the bolt shaft making the threaded section a little thicker than the bar shank. Cut thread bolts are the preferred type because they are more uniform. Rolled thread bolts work well in smaller sizes but, in larger sizes, the shank may be loose enough in a large hole to pass the threaded end. To use: carriage bolts are pushed into a hole the same size as the shank and then hammered in the rest of the way; the squarish part locks it firmly in place. 

Carriage, Built-up 
Triangular block attached to a continuous piece of lumber to make a stair stringer. 

Carriage, Sawed-out 
Stair stringer, which is cut with steps to allow the stair treads to rest on them. 

Carriage, Stair 
Stringer with stair treads attached. 

Carryback Financing

Carrying Charge 
Cash outlays necessary to maintain an investment position. 

Carryover Basis 
Basis for the valuation of property, for tax purposes, acquired from a decedent. 

Cartouche 
A scroll-like ornament. Convex and rounded architectural decorative trim. 

Cartridge Fuse 
Fuse that has terminals on each end. 

Cartridge Fuse, Ferrule Type 
Cartridge fuse with the end terminals being the end caps of the fuse. 

Cartridge Fuse, Knife Blade Type 
Cartridge fuse where the end terminals have flat, rectangular-shaped blades, which extend from the end caps. 

Carve 
Cut into shape. 

Carving 
Cutting shapes into material or forms cut out from material to be used for ornamentation. 

Caryatid 
Column with the form of a draped female figure.
