Well, I'll answer some of this. Starting with the last bit you posted, it is a Mexican ring bit. It can also be called a Turkish, Moorish, or Arabian ring bit. It has a straight bar mouthpiece with a center spade (port) that attaches to a tube running parallel to the mouthpiece. That tube forms a ring that fits around the lower jaw. The sidepieces of the bit are welded or forged to the mouthpiece, so it forms a rigid part of the mouthpiece. The sidepieces are at right angles to the mouthpiece. the rings adjacent to the mouth are for attaching the bridle, and the rings at the bottom of the shanks formed by the sidepieces, are where the reins are attached. When the mouthpiece is rotated by engaging the reins, the ring is pressed into the chin groove. The port is shorter than the shanks, and this magnifies the pressure exerted against the bars when the reins are engaged. The jaw ring fits into the corners of the mouth which keeps the mouthpiece low on the bars of the horse's mouth, which increases the severity of forces applied to the bars. The point of the ring is to allow lateral pull on the reins, such as plow reining. It is the only leverage bit that can be used with lateral pulls. That is thought to be the original reason for designing this bit. Others have already addressed the years it takes to prepare a horse (and rider) to work in a spade bit. No one has any business using this bit without the education and skill that take years to develop, and on a horse having also been educated to that level. I'd just add that the weight and design of the bit is such that the horse will correct his own head carriage just to keep the bit balanced comfortably in his mouth. The correct head carriage allows incredible lightness of signals from the reins to be responded to immediately, so engagement of the potential leverage forces is not needed to get precision performance. A spade bit should be custom fitted to the individual horse. In expert hands, this is not an instrument of torture, and functions as a beautifully crafted device for achieving precision communication. Yes, longer shanks mean more leverage. The shanks are the lever arms. The straighter they are, the sooner leverage is engaged, and the stronger the leverage force will be. This means there is greater potential to damage the tissues of a horse's mouth. No one should be using leverage bits who hasn't been educated on how they work, and developed the skill to use them. When used correctly, the shanks function to carry vibrations to the bit, which signal the horse before leverage is engaged. A shorter shank gives less time for the horse to respond before leverage force is engaged. A longer shank allows more time for the horse to respond to the vibratory signal before leverage force is engaged. So, when used correctly, the longer shank allows more time for the horse to respond, less engagement of leverage, and is less potentially harsh. In skilled hands, the lightest of rein signals send vibrations through the shanks that can produce responses, without leverage ever being engaged. What is potentially the harshest bit becomes the lightest and softest of bits when the horse has been adequately trained and the rider has the skill to use the bit without engaging leverage. The purchase increases the leverage force applied against the poll. The longer the purchase, the more poll leverage there will be. The bit mouthpiece acts as the fulcrum, and the lever arms pivot on the fulcrum. The combination of purchase length and shank length determine the overall lever arm length, and the overall leverage force applied when engaging the reins rotate the lever arm. The closer the fulcrum is to the end of a lever arm, the less force there is. So, the leverage on the poll is related to the length of the purchase from the bit mouthpiece to the bridle cheek straps. The leverage on the mouth is related to the length of the shanks from mouthpiece to reins. If the purchase and the shanks are of equal length, leverage force is applied equally to the poll and to the mouth. The curb chain is what creates a vice-like leverage force applied to the tongue, bars, lips, and the lower jaw while also stabilizing the mouthpiece from over-rotating in the horse's mouth. A leverage bit can't function correctly without it, and should never be used with out a curb chain or leather curb strap. The tighter it is, the sooner leverage is engaged. The correct fitting is with the curb strap contacting the chin groove when the shanks are rotated backward at a 45 degree angle. I have to quit. I'll try to come back and look at the rest of the bits later.

Answer 5

No. One is for a drill and one is for a router.

A spade bit is a flat drill blade with a point. The cutting edges are on the bottom edges where they stick out at right angles from the point. If used carefully it will make a decent smooth hole but it is not inherently precise and tends to get dull quickly.

A butterfly router bit is one used to cut a piece of wood to make a butterfly shaped splice to hold two pieces together. Its cutting surfaces are on its sides because it shapes the edge of the wood to fit into a correspondingly-shaped set of holes on the two boards being joined. The top part of that routed joiner fits in v-shaped hole in one board. Bottom part of it fits into v-shaped hole in other board. After you force that piece into the boards that need joining they are locked together.

Answer 6

From what I know a spade bit is a flat drill blade to drill holes. A butterfly bit is a router bit and used to join two pieces of wood.

Answer 7

Spade, paddle, flat, and butterfly are different names for the same tool.

These are good for boring holes in wood. For metal boring, you would use a "step bit" for holes larger than the chuck size of your drill.

A "butterfly bit" is also an equestrian tack item.
