1/15/2024 0 Comments Bosch vs dewalt drill bits![]() The Bosch Titanium Power Bit was the third most expensive bit in the line-up and it was only able to install 40 screws. This price, divided by the average number of screws installed, gives you the cost-per-screw.īy using this breakdown you can easily analyze two things: the best value and the toughest (cost-no-option) bit. I took those and divided by the number of bits in the packaging to get a per-bit price for the chart. The listed prices are what you can expect to pay in brick and mortar stores without any taxes included. The fact is that while fancy packaging, shiny colors and catchy tag lines might sell more product, I quickly found that, when it comes to bits, what you pay for is not necessarily what you get. Throw in some titanium plating, and you might think you have the golden ticket to screw installing pleasure. One consistent observation is that any bit marked “impact-rated” is going to cost you extra. Impact-Rated Bits: Number of Screws Installed That means that while our data is helpful and certainly real-world, it’s not comprehensive or all-encompassing-particularly as it relates to very difficult bit loads that tend to snap off the heads of bits rather than produce camout. Our testing doesn’t take into account every possible use or application of impact-rated bits (or the various bit shapes, for that matter). There are also many different ways in which the bits could have been put under different stress. ![]() In either case, testing impact bits in drywall just didn’t seem practical or helpful. This wasn’t designed to set up an unrealistic scenario-after all, high stress isn’t uncommon when you’re driving Hardiboard or cement board into plywood or composite material for a tiling job. The test material was laid out in order to create as much natural stress as realistically possible in the bit tip, so as to expedite the failure. We tested each bit multiple times with the average results factored in to establish the values used in my summary charts.Īdditional note about the impact bit testing After 4 or 5 cam-outs in a row, the bit was retired. ![]() The bits were used until they were not able to grip into the head of the screw securely and I started to experience cam-out or if the bit simply failed. All of the screw driving was done with just one hand on the impact driver handle so I could apply proper pressure but still let the tool do the work. The hard top layer of wood was intended to expedite the failure rate of the bits because of its dense composition. I placed a 3/4” piece of red oak on top of two layers of 3/4-inch plywood subfloor as the testing material. If your favorite but wasn’t tested I’d encourage you to go ahead and try this on your own and send an email to PTR letting us know your results. There are other brands not represented here, but they weren’t as easily available for me to test. I went to Home Depot, Lowe’s, Ace Hardware, Sears and Walmart. My fastener of choice was the 1-5/8″ Grip Rite drywall screw because they are both widely used and easily available.īits were chosen that are easily available in retail outlets across the country. A 20V Max DeWalt DCF895 impact driver was used for all the testing, and it was set to its highest impact/speed setting. All of the tested bits have standard 1/4” hex shanks designed to fit into the quick release chucks of cordless impact drivers. ![]() To narrow the playing field to something that is applicable to the largest audience, I chose 2-inch long #2 Phillips bits. While overseas square and Torx drive are dominant, the #2 Phillips head screw reigns king in North America. There are any number of ways in which I could have tested bits. Testing Methodology for Impact-rated Bits #2 Phillips Bits It’s going to be interesting for consumers to see whether the cost-per-screw price makes financial sense. Impact bits, on average, cost about double the price of standard bits. The goal is to see whether premium-priced bits offer additional performance. The object of this “Bit Battle” is to establish a comparison between #2 Phillips head impact-rated bits and non-impact rated bits. It quickly became very clear that knowing which ones performed better than others might be worth investigating-and might be tremendously helpful to those of us going through hundred of bits every year. During the course of that article, we found that one manufacturer’s impact-rated bits didn’t seem to last much longer than the non-impact rated bits…which concerned me, particularly since I went through over 150 bits in that test. When I was working on the premier issue of Pro Tool Reviews magazine back in March, my team drove over 7500 screws in order to test the best impact drivers.
