  • Hand Saws Hand Saws Have Evolved to fill Many Niches and Cutting Styles
    Source: https://www.garagetooladvisor.com/hand-tools/different-types-of-saws-and-their-uses/ Hand Saws Hand saws have evolved to fill many niches and cutting styles. Some saws are general purpose tools, such as the traditional hand saw, while others were designed for specific applications, such as the keyhole saw. No tool collection is complete without at least one of each of these, while practical craftsmen may only purchase the tools which fit their individual usage patterns, such as framing or trim. Back Saw A back saw is a relatively short saw with a narrow blade that is reinforced along the upper edge, giving it the name. Back saws are commonly used with miter boxes and in other applications which require a consistently fine, straight cut. Back saws may also be called miter saws or tenon saws, depending on saw design, intended use, and region. Bow Saw Another type of crosscut saw, the bow saw is more at home outdoors than inside. It uses a relatively long blade with numerous crosscut teeth designed to remove material while pushing and pulling. Bow saws are used for trimming trees, pruning, and cutting logs, but may be used for other rough cuts as well. Coping Saw With a thin, narrow blade, the coping saw is ideal for trim work, scrolling, and any other cutting which requires precision and intricate cuts. Coping saws can be used to cut a wide variety of materials, and can be found in the toolkits of everyone from carpenters and plumbers to toy and furniture makers. Crosscut Saw Designed specifically for rough cutting wood, a crosscut saw has a comparatively thick blade, with large, beveled teeth.

  • HAND TOOLS Hacksaws | Snips | Tubing Cutters | Pipe Wrenches | Screwdrivers | Utility Knives | Tool Bags
    HAND TOOLS Hacksaws | Snips | Tubing Cutters | Pipe Wrenches | Screwdrivers | Utility Knives | Tool Bags We go the EXTRA-MILE to bring new thinking to familiar tools. So they make it quicker and easier to get the job done right. We pioneered bi-metal hacksaw blades, and made them virtually UNBREAKABLE. We gave our snips pencil- ground tips to cut into tight spots, plus fused-over-molds that can’t slip off their double-tang steel handles. And we added a fourth roller to our extra-rugged, ergonomically designed tubing cutters, so they won’t walk while cutting—in addition to a built-in reamer to smooth tubing ends. When you get your hands on these and other LENOX hand tools, you won’t let go. 88 Customer Service 800-628-8810 T2™ Hacksaw Blades .....................................................90 Hacksaw Frames .....................................................91, 92 Hand Saws ....................................................................93 Snips & HVAC Tools ......................................................95 Plastic Tubing Cutters .............................................96, 97 Tubing Cutters ........................................................ 98, 99 Pipe Wrenches ...........................................................100 All-In-One Screwdrivers & Hollow Shaft Nut Drivers . 101 Locking Tradesman Utility Knife & Utility Knives ........102 Utility Blades, Safety Knife & Blades ..........................103 Soft Storage Tool Bags ................................................104 lenoxtools.comllenoxttoolls.com

  • Diamond Blade Overview
    DIAMOND BLADE OVERVIEW Variables in Cutting The segment is the part of the blade that actually does the cutting. A measured quantity of manufactured diamonds are mixed to- gether with a specific combination of powdered metals (the matrix) and processed in graphite molds at a high temperature and high pressure to form individual segments. • Diamond blades do not really cut, instead they grind through material. • The diamond crystals remove material by scratching out particles of hard, dense materials, or by knocking out larger particles of loosely bonded abrasive material. CONTINUOUS SMOOTH RIM • Provides clean, smooth cuts on: Glazed ceramic tile, marble, granite, porcelain and quarry tile • Wet and dry specs available • Sizes: 4" – 14" diameters SERRATED / TURBO RIM • Provides fast cutting with minimal chipping on: Roof tile, unglazed tile, masonry, brick, block, paver, stone and concrete • Dry specs (can be used with water) • Sizes: 4" – 16" diameters SEGMENTED RIM • Provides maximum life and cutting strength: Concrete, reinforced concrete, asphalt, masonry, brick, block, paver and stone • Wet and dry specs available • Sizes: 4" – 60" diameters 1 www.mkdiamond.com Training Manual WET & DRY CUTTING TYPES OF CUTTING • There are two basic types of cutting – dry or wet. • The best choice of blade depends upon: - the requirements of the job - the machine/tool utilizing the diamond blade - the preference of the operator DRY CUTTING DIAMOND BLADES Because of the overwhelming popularity of handheld saws, and the flexible nature of MK diamond blades to professionally handle most ceramic, masonry, stone and concrete materials, the dry cutting blade is very attractive. Dry cutting blades are also used where water is not permitted or not convenient or where so little cutting is required that set-up of water cooled equipment would be inefficient.
