7 32 drill bit

A drill is required to make a hole in any material (metal, plastic, wood, etc.). The size of the hole needed determines the drill bit size. The 7 32 drill bit is considered a general-purpose bit as it caters to various applications. A 7 32 drill bit is efficient enough for metalwork and woodwork and even drilling in concrete tiles or plastic.

Features of 7 32 drill bit

The features of any drill bit refer to its size, material, and shape. The 7 32 drill bit size means the drill bit has a diameter of 7/32th inch, which equals 0.218 inches. The diameter of 7 32 drill bit in mm is 5.56 millimeters. This particular size is frequently in demand. Even for larger holes, workers will commonly use a 7 32 drill bit at first and then further enlarge the hole. High-speed steel (HSS) or cobalt are the typical materials of drill bits to enhance hardness. In industrial applications, carbide, titanium-coated, and diamond-core bits are preferred for their higher cutting strength. While spiral-shaped twist drill bits are the norm, cone-shaped bits find application in metals, and wood-tapered bits help promote a clean finish and minimize splintering. 7 32 drills commonly come with two-point angles: 118 degrees for softer materials and 135 degrees for harder materials.

Different types of 7 32 drill bits

Different drill bits are available to cater to specific hole sizes and the type of material to drill into. Generally, the twist-drill bit is commonly employed for everyday purposes, featuring a helical-grooved shape suitable for wood, plastic, and soft metals. The spade bit, with its paddle shape and central sharp point, is ideal for larger holes and wood, minimizing the risk of splintering. Forstner bits excel at drilling flat-bottomed holes with neat edges. The brad point, akin to the twist drill but with a sharply pointed center, is well-suited for soft plastics and wood. The auger bit, equipped with a screwed tip, is designed for boring deeper holes, making it particularly useful in construction work.

7 32 drill bit substitutes

Substitutes for 7 32 drill bits are closer to 5.56mm in size. Considering a 7 32 drill bit the same as 1 4 is practical, as it is 8/32, which is the next size up. The U drill bit is slightly larger, with a diameter of 0.228 inches, making it the equivalent of a 7 32 drill bit. The number 2 drill bit is smaller but can be used as a substitute and then bored larger if needed. A 5 16 drill bit corresponds to 10/32, which is three sizes up, making it too large to substitute for a 7 32. However, a 7 32 drill bit, equivalent to 5 16 can be used interchangeably.
