If you have noticed a decrease in accuracy, attaching a vacuum system will help your machine stay accurate far longer than would be possible without it. Although Darex machines are made of the most durable material possible, it is possible to wear it out. First clean out your machine using compressed air. If this does not solve your problem then contact Darex customer service to explore further options.
Because the products are designed with different uses in mind the operations of the machines are different to accomplish different goals.
Unscrew the chuck knob, opening the chuck jaws just far enough to remove the drill bit from the chuck. Using the palm of your hand, lightly push down on the top of the jaws until they all bottom out in the chuck jaw retainer slots. The jaws will travel and secure the drill bit evenly now. The chuck is ready to use. It may be necessary to repeat these steps each time you sharpen a drill bit.
On the V290 the height of the wheel is critical to achieve correct drill geometry, each machine is different so we set the height using lasers. When a new motor is installed the height must be reset using these lasers to ensure accuracy, so you must send it back for us do this.
Remove the drill and look inside the chuck to make sure that the chuck jaws are seated properly. If not then Unscrew the chuck knob, opening the chuck jaws just far enough to remove the drill bit from the chuck. Using the palm of your hand, lightly push down on the top of the jaws until they all bottom out in the chuck jaw retainer slots. The jaws will travel and secure the drill bit evenly now. The chuck is ready to use. It may be necessary to repeat these steps each time you sharpen a drill bit. Clean out your chuck by spraying out the inside with compressed air, it is necessary to do this periodically as grit may build up inside the chuck.
Drill Doctor, Work Sharp, & Darex Sharpeners sold in the United States and Canada are designed and manufactured for 115V 60 Hz power supplies only. We assemble and ship product for a specific region’s power needs to many distributors around the world. We want to make sure you have the correct product to safely and effectively sharpen your tools.
Using a 115V machine in a location that uses 230V power sources not only voids your warranty, but also increases the chance of failure and reduces the life and performance of your tool. We want you to purchase the proper tool so you can experience the optimal performance and life of our tools.
Why is this important?
First some clarification:
- A Transformer reduces or increases AC voltage
- A Converter converts current from AC to DC
- An Inverter converts current from DC to AC
Using a simple plug adapter and no other transformation or conversion from 230v to 115v leaves the unit running on twice the rated voltage—the motor runs very hot, very fast and for a very short time before it destroys itself. A plug adapter allows the US-plug to fit into your receptacle, but doesn’t impact the power provided to the unit.
Our products do not have a ‘smart cable’ like you would find on a laptop that has a built in power supply to take input current/voltage and transform it to lower voltage. That Power Supply converts from AC to DC current at the low voltage (1-24vDC) input needed for a laptop battery or similar device.
A transformer (not a complete power supply), plugged into single phase 230v, can drop the voltage to the 115v range, but doesn’t account for the difference from US frequency at 60 Hz and Internationally at 50 Hz and may not regulate the voltage or provide sufficient amperage well depending on the quality of the device. Running on 50 Hz puts a greater strain on the motor, so while the correct voltage may be supplied to the unit, the frequency isn’t correct to get full performance (reduced power = lower efficiency = extra heat = destroyed unit). The voltage may also not be precise, out of a transformer and the 115v motors are designed to run in a specific range. High or low voltage will likely cause failures.
Forgive the long winded explanation but we want you to have a proper functioning tool that you are satisfied with now and long into the future.
The Darex V290 is not designed to sharpen cobalt drills or any thick webbed drills so the machine will not correctly sharpen these types of drills no matter what setting it is on. If you are still having problems please contact Darex customer service for help.
First adjust the depth of the point split by moving the lever under the splitting port to compensate for your problem. If the lever on your machine has come loose you will need to re-set the lever. To do this first align and sharpen a drill and leave it in the chuck, next remove the red ring on the top of the point split port. Now split your drill, if the drill is over split then you will need to put your fingers into the point split port (make sure the machine is unplugged) and turn the nut inside of the port to the left counter clockwise. If your drill is under split then you will turn the nut inside the splitting port to the right clockwise. After you have made a small adjustment re align and sharpen your drill, then re-split the drill. If the split is still incorrect continue to make small adjustments to the nut until your drill is split correctly. Once you have the nut set in the correct position move the lever under the point split port to the center and replace the red ring. If you are experiencing problems with this process please contact Darex customer service for assistance. If your machine was purchased before 2004 you may have a bent base casting, in this case contact Darex customer service for a replacement.
This problem is due to the design of the machine, your high speed steel drills will still function properly, however it is not recommend to sharpen cobalt or any thick webbed drills on the Darex V290 because of this issue.
Use the alignment paddle to adjust the amount of relief. Moving the paddle to the plus side will increase the amount of relief, moving it to the minus side will decrease relief. Different drills may require different settings to achieve the same relief, some experimentation might be required to find the correct settings for your drill. It is also important to remember that as you sharpen a drill the web size changes so it may be necessary to adjust the settings to compensate for this.
Make small adjustments on your relief settings, and check the effect on your drill. If the problem persists, contact Darex customer service for advice.
Most Darex orders are shipped using UPS ground service. If you would like change this be sure to mention your desired changes when ordering.
