| New line of diamond grit drill from Hitachi Power Tools  Hitachi Power Tools announced new line of diamond grit drill bits that are designed to power through class 5 tile, marble, porcelain, granite, slate and glass quickly and cost effectively. The five new bits, range in size from 3/16" to 3/8", offer cost efficiency and placement accuracy for DIYers and professionals who are performing residential and commercial applications. These bits can be required for installation of the basin, cabinets, radiators, sink, bath, hand rail, toilet bowl, towel rail, toilet roll holder, shower unit, soap dish, shelves, tooth brush holder, mirror, lights, curtain rail, towel hook and shower frame.These bits, ranging in sizes 3/16", ¼", 9/32", 5/16" and 3/8", provide the user with a bit that is high in speed and durability. These bits feature raised lips with diamond grit particles that are uniquely sintered in place using a patented process. This process allows the diamonds to adhere to the bit and not grind down as quickly as other sintering processes. To use freehand, the user accurately positions the bit at an angle to pilot the hole. As the hole edge is defined, the user can slowly center it directly above and begin to drill down eliminating the risk of drill bit wander. As the bit drills down through material, the hollow barrel of the bit creates a core that helps guides the drill and keeps it on track with no chance of skating. This feature improves safety to the user, accuracy of the hole placement and protects the material from any damage from bit slippage. A convenient core removal ejection slot pushes the core material out from the bit ensuring hole after hole can be drilled without delay. Also, the drill does not have to be held perfectly perpendicular to the tile to avoid breakage. The Hitachi diamond grit drill bit bodies are constructed of hardened and tempered thin wall alloy steel. They require water lubrication during use. This can be simply applied with a spray bottle - producing a small puddle of water that is spiral fed down the reverse flute threads on the bit to continuously supply water to the cutting edge, cooling the bit tip, and extending its life. Additionally, if the hole is being drilled into a vertical surface, Hitachi offers a Drill Guide and Water Cooling System. This system is comprised of a drill bit guide for the five different sizes and helps direct the bit into the exact spot for accurate placement of a hole. Four suction cups on the back attach the system to the tile or glass surface. The user selects the guide hole that is needed and moves a water reservoir cup to the closed position over the hole selected. The reservoir cup is filled with water. The guide is lined up with the hole mark and stuck to the surface. Once ready to drill, the user moves the reservoir to the On position; places the drill into the guide and drills the required hole. A steady stream of water will flow to the bit. Once the hole is finished, simply move the reservoir back to the Stop position and remove from the wall. write your comments about the article :: © 2006 Construction News :: home page |
