The two most common Drill Bit Angles, or to be precise, Drill Bit Point Angles, are 118 degrees and 135 degrees. The point angle is measured like this: The choice of which angle to use is largely based on the material being drilled.
By choosing the right drill point configuration and included angle, you can receive longer tool life, more precise hole geometry, cleaner breakthrough and improved job productivity. If you have questions about the right drill point for your job, just ask us at Regal Cutting Tools.
More simply, it is the angle between the lips in the side view of a twist drill. The typical value of the point angle is 118°. This term is pretty self-explanatory. The neck is between the shank and the flute. The neck allows space for chip evacuation and prevents the shank from rubbing during deep-pocket milling applications.
The drill bit point angle refers to the included angle between the two faces of the cutting edges. Since both edges are sharpened equally relative to the drill shaft, the drill point angle technically refers to the sum of the angles of both faces.
Understanding the drill bit angles is a crucial factor in achieving successful drilling operations. Knowing the different drill bit angles and considering factors such as material type, drill bit coating, and drill speed, you can master the optimal drilling angle for each specific application.
Guide your 3/8 in. or 1/2 in. drill at any angle from 45 to 90 degrees with precision using this angle drill guide. The drill guide features a positive-stop depth control, spring return to keep the guide ready and protractor for easy angle settings in 5 degree increments.
The angle at which a drill bit should be sharpened depends on the material being drilled. For example, wood and plastic require a sharper angle of 60-90 degrees, while metal requires a more obtuse angle of 135 degrees. Consult a drill bit angle chart to determine the correct angle for your specific application.
30 45 90 Degree Angle Drill Guide Jig with 4 Bits. Nice quality jig, made of aluminum with steel inserts. There are three drilling angles of 30, 45 and 90 degrees, and each drilling angle has 4 sizes of guide holes: 3/8 inch (9.52 mm), 5/16 inch (7.93 mm), 1/4 inch (6.35 mm), and 3/16 inch (4.76 mm). 4 drill bits are included.

1. After installing a drill bit in the Angle Drill Guide and attaching the drill, position the tool on your work material. 2. Align the tip of the drill bit with the desired location on the work material. 3. To prevent the Base (6) from moving on the work material during drilling, you can use the Anchoring Pins (5). Press the Anchoring Pins (5 ...
