【Product Size】Drilling diameter：38mm | 1-1/2", Round Shank Dia.: 10mm | 2/5", Drilling depth: 60mm | 2-3/8", Total length: 94mm | 3-11/16", for hardwoods choose the corresponding size, for softwoods choose a size smaller by 0.2-0.5mm
【High Quality】Positioning drills and blades are made of YG8, hardness ≥ 91HRA, bending strength up to 2200N/cm2, resharpenable. The shank rod is made of No. 45 steel, heat-resistant and corrosion-resistant. After quenching, the hardness is extremely high, effectively avoiding shank bending during use
【2.00mm Super Thick Blade】Adopts industrial grade 2.0mm thickness YG8 blade, which extends the service life by 10 times compared to 1.3mm thick blade
【3 Flute Design】The drill has 3 support points, making it easier to position and cut smoother compared to 2 blades, effectively preventing skewing and burning the wood. It is very user-friendly for beginners
【Note】 The drilling process needs to be kept vertical and it is recommended that a tool such as a vise be used to keep the material stable so that a smooth, accurately sized hole can be obtained. Set slow drilling speed till the drill bit is completely located, then gradually accelerate speed. The rotational speed is controlled at 2200~2500RPM for better effect
【Widely Applications】 The Forstner hole saw is perfect for wood,plastic,plywood,solid wood boards,MDF,plastics,furniture,door hinge,desk,etc.Note: Can not drill metal and non-ferrous metal
【Warm Tips】For large-size Forstner drill bits (≥60mm), it is best to use machines with good fixation performance for drilling operations, such as drill presses, bench drills, vertical drill presses and vertical electric drills, etc. If you must use a hand electric drill to operate , be sure to use a high-power electric hand drill, and it is best to use it with a vise with good fixation effect. Otherwise, good hole opening effect will not be achieved
