Fasteners And Fixings: Why Do My Drill Bits Keep Breaking?

Nothing can be more frustrating during a home improvement project than a dill bit breaking. After all, there are only so many of these fasteners and fixings in each drill set, and constant trips to hardware store to purchase new ones can strain your wallet and your productivity. If breaking drills is always the case, here are some tips that will help you to figure out a solution.

 

Fasteners and Fixings- Understanding The Drill Bit Design

 

One of the most common reasons for failure of one of these fasteners and fixings is a failure in the drill bit design.

  • Poor Drill Bit Strength- The drill is liable to break with large amount of deflection at the end of the bit. You can control this however, by changing the web taper and the thickness.
  • Little Chip Pocket- If you subject the bit to an extreme twist, the middle of the flute could break. Changing the web taper and thickness can also help prevent this from happening.
  • Unnecessary Long Flute and Body- If the flute and body of the drill bit are too long, the accuracy of the bit will be incorrect. Make sure the bit is an appropriate length before you attempt to use the drill bit.

 

Manufacturer’s Fault

 

The factors surrounding the manufacture of the drill bit may also facilitate these problems with the bit.

  • Geometries of the Drill are Unbalanced- This can result to accuracy problems relating to gaps and chipping.
  • Worn Diameters- If the diameter is worn, the cutting resistance will increase and the drill bits will often experience breakage.

 

Best Quality Fasteners and Fixings- Conditions Of Drilling

 

You need to carefully select drill bits for each fasteners and fixings you are using. Using the wrong drill bit will sure result to chipping and breaking. Here are just a few more conditions which can affect how secure your bit is.

  • High and Low Chipload- You may witness inaccurate holes, increased thrust and breakage if you progressively use high or load chipload. To this end, you must ensure that the chipload of your drill bit is correct before you use it.
  • Spindle Speed- A high spindle speed can increase the bit’s resistance to cutting. On the other hand, using low spindle speeds can increase friction between the bit and material. This friction causes heat and can lead to broken bits. Applying the right speed can ensure prevention of this type of breakage.
  • Backup Boards- When you are working on a material with backup board, you may likely have to deal with the generated swarf particles. The swarf particles can stick with the drill bit and cause it to break. In order to avoid this, you must drill to the recommended depth.

 

It is only when you know the possible causes of broken bits can you make any effective move preventing it. Make sure drill bits are always clean and be sure to use the appropriate ones with your materials to lessen the chances of breakage. Affordable Fasteners and Fixings
