Broca Forstner Bosch 50 mm de diâmetro, 90 mm de comprimento, modelo 2609255293

Forstner drill bit Bosch 50 mm diameter, length 90 mm, model 2609255293 is a precision woodworking bit designed to create flat-bottomed, clean-edged holes in solid wood, veneered panels and wood-based materials. With a centring tip and short pilot point it enables accurate positioning and neat entry, delivering high-quality bore surfaces and minimal tear-out.

Advantages

The Bosch Forstner drill bit features two cutting edges and a peripheral cutting rim for smooth cutting and good chip removal. Heat-treated steel with cutting hardness of at least 50 HRC provides wear resistance, while the reduced cylindrical shank (maximum 10 mm diameter) allows use in many hand drills and drill presses. The short centring point ensures precise start and reduced wandering when drilling.

Suitable for

• Drilling flat-bottom holes for furniture fittings and hinges
• Creating clean-edge holes in hardwood, softwood and veneered panels
• Applications in cabinetry, joinery and repair work

How to use

Fit the reduced cylindrical shank into a compatible drill chuck or drill press. Mark the hole centre and position the centring tip on the mark. Start drilling at low speed to avoid slipping, then increase speed while applying steady pressure. Use appropriate feed and speed for the material to achieve clean edges and flat-bottom results. Clear chips periodically to maintain cutting efficiency.

Recommendations

Use the Bosch Forstner drill bit for precise hinge and fitting holes in furniture and cabinet work. For veneered panels and thin materials, control penetration depth and support the workpiece to prevent breakout. Sharpen or replace the bit when cutting quality declines.
