3 (76mm) Forstner Drill Bit for Precise Woodworking with Durable Carbide Thickness Ideal for Hard Wood, Plastic, Plywood

About this item

• 【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
• 【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
• 【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
• 【Product Size】Drilling diameter：76mm | 3", Hex Shank Dia.: 12mm | 15/32", Drilling depth: 60mm | 2-3/8", Total length: 94mm | 3-11/16"
