  • 2. Sturdiness Upholstery sewing involves handling heavy materials, which means your table needs to be robust. A solid table reduces vibration and provides stability during sewing, ensuring precision in your work.


  • A lock stitch is created by interlocking two threads—a top thread and a bobbin thread. The top thread is fed through the needle and forms a stitch on the front of the fabric. The bobbin thread, located in a lower compartment of the machine, loops up to meet the top thread, forming a secure stitch that is often used for a wide array of sewing applications. This type of stitch is characterized by its tightness and durability, making it suitable for sewing heavier materials such as denim and canvas, while also being gentle enough for lighter fabrics.

  • The 'tapered' aspect of these drill bits refers to their unique geometry. The bit's body tapers inward towards the cutting end, which not only enhances its stability during drilling but also ensures a secure fit into the drill rod. This design allows for better torque transfer and resistance against bit slippage, ultimately increasing drilling speed and overall productivity.
