You can plunge with both types of bits, so they’ll both work for, say, cutting mortises. But because most spiral bits are ground on the tip end of the flute, somewhat like a drill, you can plunge straight down as far as you like, without stopping. You can’t really plunge any deeper than about in. with a typical straight bit. Inspect the end, and you’ll see why. On most straight bits there is a space above the web, between the cutters, where no cutting takes place during a straight plunge because there is no cutter overlap. Chuck a straight bit into your drill press and plunge it into a piece of wood. After about in., the middle of the bit bottoms out. To go any farther, the bit has to abrade the wood away in this middle area.

It is found on the lathe. Technically, it is part of the carriage. Available in an H shape, the saddle is designed for supporting across slide movements.

The increasingly popular spiral router bits borrow technology from the metalworking industry. Spiral bits look like drill bits and are most often made of solid carbide, so they are super sharp and leave a superior cut on wood. Two flutes ground around the body of a spiral bit smooth vibration by spreading the cutting action over a longer edge. With their drilllike point, spiral bits are also better for plunge-cutting. All of these advantages also mean less wear and tear on the router. But don’t throw out all of your old straight bits just yet.

This doesn’t mean you can’t cut mortises or plunge with a straight bit. You just have to sweep the router while you are plunging. You should probably cut mortises in passes not much deeper than in. anyway, but with a straight bit, such shallow passes are just about a must.

The new solid-carbide spiral bits come with some disadvantages. The first is that the cutters are expensive. A typical solid-carbide spiral bit is likely to cost at least $50. A similarly sized straight bit with carbide-tipped cutters will run somewhere in the range of $7 to $23. With a cost differential that large, you will want to know what you are going to do with this bit and that you will use it often enough to get your money’s worth. To highlight other differences, let’s compare the qualities of spiral bits and straight bits.

It is the horizontal structure of the lathe on which the casting for the tool post and tailstock both mount to and slide as needed. Almost all lathes comprise a bed except CNC lathes. CNC lathe machines have a vertical beam to minimize the accumulation of the swarf.

It is a movable casting secured on the end of the lathe parallel to the headstock. Popularly known as a loose head, it is used for installing drill clamps for drilling center holes to support longer workpieces.

Irrespective of the length and shape, it holds the workpiece securely. This mechanical device is attached to a lathe through screws fitted on the spindle nose. There are two types of chucks – 3-jaw or self-centering chuck and 4-jaw or independent chuck.

Lathes are one of the oldest yet versatile machining tools, which have evolved and adapted effectively with time. This is why they still find uses across manufacturing units of various industries. Mainly preferred for cutting and turning operations, lathes also perform drilling, sanding, and facing effectively. Not to be confused with a milling machine, lathes use a rotary cutting tool that moves along axes to make the desired cuts. Today, the CNC lathe machine has become the industry standard for manufacturing precision components and parts. Owing to the immense popularity of CNC machining, it’s wise to use a CNC lathe machine that transforms production processes. Are you intrigued to know more about them? What is the structure of the lathe? This post answers the same. So, stay tuned.

Synopsis: Pat Warner compares the qualities of spiral bits and straight bits. Both have “plunge-ability,” but spiral bits leave a cleaner edge; straight bits come in many sizes and bearing configurations. Sharpening spiral bits is difficult, if not impossible, and they can be risky to use. Warner says there’s no clear winner; you must pick the best bit for the job, and this article helps clarify which bit is better for different applications. Side information tells you how to distinguish an upcut bit from a downcut bit.

Carriage is one important component located between headstock and tailstock. This part of a lathe is responsible for supporting and guiding the tool against the workpiece throughout the process.

It features a cylindrical shaft, allowing a longer workpiece to pass through it. It is responsible for holding the workpiece securely. So, the force of the tool can’t overpower.

It is designed to support the cutting tool and tool post in different positions. It is one of the important components for turning angles and boring short tapers.

The three basic cutter configurations for spiral bits are up-cut, down-cut and a combination of the two, known as a compression bit. A down-cut bit sends the chips downward; an up-cut bit sends them up toward the shank. (On a router table, all directions are reversed.) Besides directing the chips, the advantages of these configurations are best illustrated by the quality of cut, especially on veneered plywood.
