Protractor for drill grinding Vogel Germany 472018, multi-purpose

Universal Twist Drill Grinding Gauge. It is used to check and adjust the grinding angle of drill bits, ensuring accuracy during grinding. A check gauge is available so the user can quickly test-fit the drill during machining; it is made of stainless steel and mounted on the back of the gauge. The clamping head for the drill point tilts, making it easy to open and close during operation.

• Measuring dimensions and checking the drill point angle: The gauge has common angle steps such as 60°, 118°, 120°, 130°, 140°, 160°. Determine the grinding angle suited to each type of material.
• Determining grinding deviation: Supports checking the balance between the two cutting edges of the drill bit. The drill bit does not run off-centre during use.
• For drill bits with diameters up to 100 mm: Suitable for both small and large drill bits.
• Additional measuring scale: Some versions integrate a scale for determining distance and depth.
• This tool is useful for machinists and maintenance technicians. Those who work with drill bits on a regular basis.

The universal drill grinding protractor supports checking and correcting the grinding angle of drill bits. This way ensures accuracy during machining. Designed from special steel that has been hardened, surface-ground and polished. The gauge measures drill diameters from 0 to 70 mm and supports common angles such as 60°, 118°, 120°, 130°, 140° and 160°.

The stainless steel Drill Point Check gauge plate on the back of the protractor serves to quickly check the grinding angle of the drill bit. It is used as follows:

1. Determining the drill point angle: Place the drill point into the pre-cut slots on the gauge plate. If the drill angle matches one of the slots, the drill bit has a standard angle (60°, 118°, 120°, 130°, 140°, 160°).
   If it does not match, the drill bit needs to be reground to the correct angle.
2. Checking the deviation of the two cutting edges: Place one cutting edge of the drill bit flush against the straight edge of the gauge plate. Observe whether the two cutting edges are balanced. If one edge is longer than the other, regrinding is needed to ensure symmetry.
3. Checking the length of the cutting edges.: Some gauge plates have graduations to check whether the two cutting edges are equal. If the cutting edges are not equal, the drill bit will run off-centre when drilling. Some types have a straight edge instead of graduations.

You use the Drill Point Check gauge plate to quickly check the drill angle. No other dedicated measuring instruments are required. They are useful for machinists and maintenance personnel. Its versatility also lies in this feature of the gauge.
