The Grizzly G9849 Magnetic Base Dial Indicator is an essential tool for any metalworking shop or machine tool setup. This versatile and accurate measuring instrument is designed to provide real-time feedback on the depth or distance of cutting tools, drills, or other machine components during the manufacturing process.
The heart of the G9849 is its robust, adjustable magnetic base. Constructed from cast iron, it offers superior holding power for ferrous workpieces and can easily be clamped to non-ferrous materials using the included clamp. The base can be tilted up to 30 degrees in any direction to accommodate various applications.
The dial indicator itself features a 1-inch (25mm) dial face with a precision-machined glass window, ensuring clear and easy-to-read measurements. The dial is graduated in both inches and millimeters, providing flexibility for users working in different measurement systems. The needle-type indicator moves smoothly and accurately, making it easy to detect even the smallest changes in depth or distance.
The G9849 also includes a handy adjustable pointer, which can be locked into place to track specific depths or distances. This feature is particularly useful when setting up drill presses, milling machines, or lathes for repeated operations.
The indicator comes with a protective carrying case, making it easy to transport and store when not in use. Overall, the Grizzly G9849 Magnetic Base Dial Indicator is an indispensable tool for anyone seeking precision, accuracy, and versatility in their metalworking or machining projects.
The Grizzly G9849 Magnetic Base Dial Indicator is a versatile tool designed to measure and indicate the run-out or parallelism of various machine components. In this analysis, we will discuss the key features, advantages, and disadvantages of this dial indicator to help you make an informed purchasing decision.
**Key Features:**1. Magnetic base for secure attachment to ferrous surfaces
2. 3-inch (76mm) dial with a 0.001-inch graduation
3. Quick-release lever for easy mounting and demounting
4. Rear parallax error correction for increased accuracy
5. Hardened steel pointer with a diamond tip
**Advantages:**1. The magnetic base provides strong and stable attachment to ferrous surfaces, ensuring accurate readings.
2. The large 3-inch dial offers high-visibility readings, making it easier to read even in poorly lit areas.
3. The quick-release lever simplifies the mounting and demounting process, saving time and effort.
4. The rear parallax error correction minimizes the risk of inaccurate readings due to parallax error.
5. The hardened steel pointer with a diamond tip is durable and resistant to wear, ensuring long-lasting performance.
**Disadvantages:**1. The magnetic base may not adhere well to non-ferrous surfaces, limiting its versatility.
2. The dial indicator does not come with a protective case, which may require additional investment for safe storage and transportation.
3. The maximum indicated travel is only 0.030 inches (0.76mm), which may limit its applicability for measuring larger run-outs or parallelism errors.
**Ending Conclusion:**The Grizzly G9849 Magnetic Base Dial Indicator is an effective and reliable tool for measuring run-out and parallelism on ferrous machine components. Its large, high-visibility dial, quick-release lever, and rear parallax error correction contribute to increased accuracy and ease of use. However, its limited applicability to non-ferrous surfaces, lack of a protective case, and relatively small maximum indicated travel are potential drawbacks.
**Recommendation:**If you frequently work on ferrous machine components and require a dial indicator with a large, high-visibility dial and quick-release lever, the Grizzly G9849 Magnetic Base Dial Indicator is an excellent choice. However, if you need a dial indicator for non-ferrous surfaces or require a larger maximum indicated travel, you may want to consider alternative models. Ultimately, the decision depends on your specific application requirements and preferences.
The dial indicator features 0-1-Inch travel and has a resolution of 0.001-Inch. Magnetic base engages with just the turn of a switch and allows pinpoint adjustment. Grizzly Magnetic Base/Dial Indicator Combo G9849. Precision measurements and set-ups have never been so easy.
