This full set of cutters is distinguished by its excellent workmanship and ease of handling. It will enable you to create both external and internal screw threads with many available dimensions.
Dies are equipped fitted with 2 knives in sizes 1 1/2 in. (38 mm) and up. Dies in sizes 1 1/4 in. (32 mm) and above have two handles. The V-profile knife and the tap can only be sharpened from the inside.
When possible, use only dense and fine-grained woods - beech, cherry and pear, for example. Woods such as pine and oak are unsuitable. Soaking the wood to be threaded in oil for two days makes it more pliable and reduces the risk of tear-out of the raised threads.
