MOLLOM 3-1/2" (89mm) Carbide Forstner Drill Bit | 2.0mm Thickness YG8 Carbide Tipped, Hinge Cutter Tool For Hard Soft Wood, Plastic, Plywood, Precise Woodworking
Product Features
- Product SizeDrilling diameter:89mm | 3-1/2", Hex Shank Dia.: 12mm | 15/32", Drilling depth: 60mm | 2-3/8", Total length: 94mm | 3-11/16"
- High QualityPositioning 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 BladeAdopts industrial grade 2.0mm thickness YG8 blade, which extends the service life by 10 times compared to 1.3mm thick blade
- Super AccurateWe use a fully automated production line, the product accuracy is up to 99%, the error of drilling holes is within 0.1mm, it is a good choice for high precision drilling work (for hardwoods choose the corresponding size, for softwoods choose a size smaller by 0.2-0.5mm)
- 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 TipsFor 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
