| Hitachi expands its line of diamond grit drill bits  Hitachi Power Tools announced an expanded assortment of its revolutionary line of diamond grit drill bits ranging in size from ½" up to 1". Designed to power through class 5 tile, marble, porcelain, granite, slate and glass quickly and cost effectively they significantly outperform the standard carbide glass and tile bits available on the market today, both in speed of drilling and the number of holes that can be drilled per bit. They offer cost efficiency and placement accuracy for serious DIYers and professionals who are performing residential and commercial applications.First released exclusively by Hitachi in November of 2006, the initial round of diamond grit drill bits range in size from 3/16", ¼", 9/32", 5/16" and 3/8" and have received overwhelming industry response recently receiving Editor Choice Awards from Tools of the Trade Magazine (May/June 2007) and El Neuvo Constructor (June 2007). Due to the favorable response and being the ultimate solution to tile and glass drilling challenges to date, Hitachi has grown the offering by four to include ½", 5/8", ¾" and 1" diamond grit drill bits to tackle even more applications. The demand for granite, glass tile and hard Class 5 materials in bathrooms and kitchens is growing. Up to 30 holes can be required to install fixtures through these hard materials. The challenge with this trend is that the existing methods and accessories available to drill are too slow, not durable and not cost effective for drilling more than a few holes per bit. Hitachi's proven solution is the diamond grit drill bit series. 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. 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. The diamond grit drill bits are essential for the weekend warrior and the pro-user who does tiling all day for a living to make installing and finishing a kitchen or bath much simpler. write your comments about the article :: © 2007 Construction News :: home page |
