About this item

  • Wide Range of Sizes and Qunatity Option: We offer a variety of sizes for these square hole drill bits and chisels, including 7/30 Inch (6mm), 1/4 Inch (6.4mm), 5/16 Inch (8mm), 3/8 Inch (9.5mm), 7/16 Inch (11mm), 1/2 Inch (12.7mm), 9/16 Inch (14mm), and 5/8 Inch (16mm). Additionally, we provide different combinations of sizes to cater to your specific needs.
  • Quality Material: These square hole drill bits and wood mortising chisel set are crafted with high-speed steel, ensuring durability and longevity. The HRC48-50 hardness guarantees their ability to withstand heavy-duty woodworking tasks.
  • Versatile Woodworking Application: Designed specifically for woodworking, these square hole drill bits and chisels are perfect for creating precise square holes in various wooden materials. Whether you're working on furniture, cabinets, or other woodworking projects, these tools provide the accuracy and efficiency needed to achieve clean and professional results.
  • Enhanced Precision and Finishing: When using these drill bits, you can achieve tidy square holes. However, for the finer details, it is recommended to chisel by hand. This additional step ensures that the square holes have a polished and refined finish, enhancing the overall quality of your woodworking projects. The combination of drilling and chiseling allows for greater precision and control over the final result.
  • Heat Management for Prolonged Use: To prevent overheating and potential damage to the drill bits, it is advised to use cutting fluid during usage. This fluid helps to keep the bits cool, even during fast rotary friction. By maintaining a lower temperature, the drill bits can be used for longer periods without compromising their performance. This feature is especially beneficial for those working on extensive woodworking projects.

The picture did not specify the size of the shaft of the square pieces. The sharpening is not the best but they are workable.

To start with, the listing says these square hole mortising bits come in inch sizes. What I received was a set of metric bits. That's something I may or may not be able to work around depending on the project.Metric or not, a square mortising bit is basically a drill bit coupled with a square shaped chisel. Like any chisel it needs to be very sharp to do its job. The chisel part of these bits are anything but sharp. The machining process has left the cutting edges jagged, curled and wavy.I thought about sharpening them, but the milling on the inside of the bits is too rough to make a good cutting edge, and I'd likely ruin the squareness of them anyway (not that they are all that square now). Someone with some mad sharpening skills could probably make these work, but a better use of one's time would be just buying a better product.I might try my hand at sharpening these someday, but for now I'm going to pass on using these.
