Today on the Mister Worker ™ blog we are in the company of Massimo Castelnovo, Trade Manager at Stanley Black & Decker, to help our customers in choosing the Lenox hole saw that best suits their needs.
M.C.: The hole saw is an accessory that cannot be missing in the toolbox of a professional worker, or in the assortment of a DIY enthusiast. When choosing a hole saw, the most important factor to consider is the type of material on which the drilling must be carried out. Hole saws can in fact fact guarantee a reliable and precise hole on different types of material, such as wood, nail-embedded wood, MDF, laminate, aluminum, stainless steel, cast iron, non-ferrous metals, plastic, plaster, fiberglass, Corian, ceramic, porcelain stoneware, marble, slate, brick, and others. In addition to the material of the object to be drilled, it is necessary to consider the material of the hole saw, which can be bimetallic, diamond or carbide tipped.
In the Lenox range there are three types of hole saws:
M.C.: A quality hole saw has a structure made mainly of high-strength steel, it must have a robust wall and a reinforced bottom plate to significantly reduce vibrations. In addition, especially in bi-metal hole saws, the tooth design and the sharpness of the teeth are fundamental for the durability of the product. The presence of a percentage of cobalt equal to 7/8% guarantees the resistance of the saw against breakage even during demanding applications.
M.C.:The brand Lenox has been active in the global marker for more than 100 years. It has always been synonymous with quality and performance in the production of accessories dedicated to cutting and drilling operations. The first Lenox hole saws entered the market in 1959, since then Lenox has always stood out for the excellent quality/price ratio of its bi-metal, diamond or carbide tipped hole saws.
M.C.: The most important range in this product category is certainly that of bi-metal hole saws. It is a complete range with the possibility of drilling holes from a minimum diameter of 14 mm up to a maximum of 210 mm. These saws are able to guarantee excellent results in terms of speed and durability on different materials thanks to the production technology which, for some processes, is covered by patents deriving from the great experience gained by Lenox in the sector of band saw blades for industrial applications.
M.C.: The patented T3™ SPEED SLOT technology has greatly improved Lenox Bi-metal hole saws. Thanks to an exclusive design and an aggressive tooth shape, these products show an optimal cutting performance, speed and precision on different materials. These hole saws also require less pressure when drilling and reduce the tendency to block on thinner materials. In the case of drilling on wood, the SPEED SLOT side openings guarantee rapid material removal even on depths of 45 mm.
M.C.: You surely need an arbor to engage the hole saw of the required diameter. Generally, there are two arbor sizes, one for diameters from 14 to 30 mm and one for diameters from 32 to 210 mm. In the Lenox range there are also arbors called SNAP-BACK which guarantee a quick and tool-free replacement of hole saws.
Another fundamental accessory is the step drill bit that is mounted on the spindle, and is necessary to start the hole before moving on to the required saw diameter.
M.C.: In the very near future, September 2020, Lenox will renew the range of hole saws with hard metal inserts.
The new products will guarantee a service life 50 times longer than the current range, keeping prices in line with the current price list.
Subsequently, the main range of Bi-metal hole saws T3™ SPEED SLOT will also be updated with the new T4™ technology. Hole saws will be more performing and durable and Lenox will always supply customers with high quality products.
