This review is for the Bosch SB5013P Rapid Feed Spade Drill Bit set. This set includes 13 spade drill bits with a 1/4″ shank. As you can see from the pictures they are all stored in a nice Nylon case that closes with a Velcro strap. This set comes with the following sizes – 1/4″, 3/8″, 1/2″, 9/16″, 5/8″, 11/16″, 3/4″, 7/8″, 1″, 1-1/8″, 1-1/4″, 1-3/8″, 1-1/2″.
According to Bosch their feed bit system leaves cleaner, smoother holes with reduced splintering. One key advantage is, it supposed to leave less break out material on the back of the hole than traditional bits. The reason is Bosch has cutting spurs on the edge that score the material before the cutting edge removes the material and this is what produces a cleaner hole.
For our review we ran the Bosch speed bits against a tradition bit to see which provided a faster, cleaner cut. As you can see by the video below, the Bosch cruised through the material with no problem at all, in fact, it was faster than the traditional spade bit. One item that did not show up on the video was we went through a piece of 3/4″ plywood with the Rapid feed and traditional bit. On the back side of the plywood, after we cut through the wood, the Rapid feed produced a better, cleaner hole. There was less splintering.
We found this kit to sell for between $20 and $40 online.
Over all we like these bits. We like the case that comes with these bits as they will always be kept together. The case is a nice small storage place that doesn't take up a lot of room in your tool bag. The bits themselves we like. They produced a nice clean cut and ripped through the material. For the price of these bits, we would recommended buying these to add to your inventory.
