What Is A Split Point Drill Bit
Drill bits come in a variety of point configurations with each designed for specific uses. Each type of point design has its own uses. There are 6 types of drill points: Read: what is a point drillStandard industrial drill or conventional drill – A standard point drill or a v-drill with an included angle of 118 degrees with cutting angles suitable for cutting metal. Standard point drills specifically designed for cutting wood typically have a longer sharp angle (ie 80 degrees). A longer 80’s point can sometimes work better on wood if you’re having problems with excess debris on the backside after drilling through the wood. The 118-degree point is designed to be a versatile spot and will cut almost any material. If the standard drill bit does not give the desired results, one of the other types of drill may be needed.Point Separation Drill – this type of bit usually has corner points including 135 degrees and is designed for cutting metal. The standard drill has two cutting edges but there is a section in the center of the drill called the chisel edge that doesn’t actually cut, but chisel the material. The chisel edge can also cause the drill bit to traverse the material when you are trying to start cutting the drill at a specific location. The Split Point drill has two additional edges that are sharpened into the chisel edge, making the entire drill one long cutting edge. This reduces the amount of pressure required to make the drill bit cut. The Split Point is also self-centering which means the drill starts to cut exactly where it comes into contact with the material. These features are designed for drilling in metal but may be beneficial in some harder woods.Brad-Point drill bit – Why use a brad-point drill? A sharp tip drill should provide the cleanest, straightest, and most accurate sized hole in wood of any reasonably priced tool on the market today. The bar in the center of the point allows for precise positioning at the start of a hole even when the hole is not 90 degrees from the surface. Outer edges thin the grain and leave a clean edge around the opening eliminating the need for sanding. The branch continues to cut the wood while drilling and creates a hole of the correct size. In most woods, drill bits also help create cleaner edges when drilling through the back of the wood. We have worked with thousands of customers to manufacture Brad Point Drills to meet their needs. We offer Brad Point Drills in any size including Wire Gauge, Letter Size, Metric Size and longer or shorter lengths. If there is a need for a size not mentioned in these, we can take standard sizes and grind and/or cut to the special size needed. We use industrial quality High Speed Steel domestic drill bits designed for metal cutting and re-machine them for wood cutting. As a result, the Brad Point Drill is made tolerable when it comes to metal working with cutting edges that last longer than standard woodworking tools. There are basically two types of brad point designs that we use. One works best on hardwoods and the other works best on softwoods. Brad Point drills specially designed for softwoods generate too much heat and are difficult to push in hardwoods. Although the Brad Point Drill is specifically designed to cut hardwoods that will cut softwoods, the aggressive cutting blades tend to lift the weak fibers of the softwood, resulting in a torn edge around the opening. All the Brad Point Drills that we manufacture and display in our catalog are specifically designed for hardwoods and work well for most applications.
The difference between the two types of points is in the design of the outlines. Brad point drills work best on softwoods with rounded spurs, which help keep the wood grains down while cutting them out. There is a certain rubbing that occurs between the outline spur and the wood before it is cut. The spikes on the Brad Point Drill for hardwoods become sharp and simply cut away the harder grains. No rubbing occurs and therefore no unnecessary heat is generated by the cutting action Read more: What channel is special on the fiosIf the Brad Point Drill is needed for softwood, please specify “for softwood” in your order list. Another feature of the Brad Point Drill that can affect its cutting ability is the actual brad or pyramid point in the center. Although the sole purpose of the brad is to guide the drill through the material and keep it running straight, the shape of the brad can affect the result. The brad itself doesn’t actually cut the wood. It mainly scrapes and pushes the wood aside. If the base of the braid is too thick or fat, the drill will be much harder to push, especially in hardwoods. A bushing that is too thin will allow the drill to cut freely but may break in the process. It is very important that the lanyard is centered exactly at the point of the drill bit. An eccentric brad can cause the drill to cut larger than it actually is. Often different lengths on brad to achieve different results. A longer braid can be used when it is necessary to drill a hole in an angle instead of drilling straight into the wood. Up to 45 degrees or even 60 degrees from the vertical can be drilled by extending the length of the brad. A shorter brad than usual may be required in cases where the hole needs to be drilled close to but not through the back of the material. material.

This point creates a clean hole and prevents the drill bit from breaking the Plexiglas when drilling through the back.Screw drill bit Found strictly on wood cutting tools, these types of spots are sometimes referred to as self-feeding points. The screw point is designed to support and control the feed rate for that tool. In other words, the screw point controls the cutting speed of the tool and eliminates all need to push the tool. A must when drilling large holes with a hand-held device. The disadvantage of a tool with a screw point is that unless the screw point is replaceable, the tool will only last until the screw wears out. That may not take long in hardwoods.Taper point drill bit – this type of point is specially designed for machining the shank and thread of standard wood screws. Available in sizes and lengths to cover a wide variety of screws. Some customers have had success using this drill to cut holes when a clean edge is required through the back. The taper point drill penetrates gradually and produces clean edges on both sides.
