French DIAGER five grooves and six edges cement drill tail bit (AH20034)

The DIAGER five-groove six-blade cement drill tail drill bit, originally imported from France, is suitable for five-groove force-free hammer drilling. It is a five-groove steel bar drill bit that can pass through steel bars. The five-groove hammer drill bit adopts super-hard tungsten steel cutter head, which is hard and impact-resistant. The alloy cutter head has a positioning convex point design, which can automatically position , and the shoveling effect is easier to crush concrete. The hole diameter is accurate and the position is not offset. 6 main cutting edges maintain simultaneous cutting in multiple directions, increase drilling speed, and ensure stable and balanced drilling force through automatic positioning.

Product Features:

• The French DIAGER five-groove six-blade cement drill tail drill bit is a drill bit that can drill through steel bars . It uses a super-hard alloy cutter head, which is hard in material, impact-resistant, has a low wear rate and a long service life.
• New grooves strengthen the axial drilling force and enhance the earthquake resistance
• 3 alloy blades, 6 main cutting edges, automatic center positioning, accurate positioning, easier to crush concrete
• The alloy cutter head has a positioning bump design, automatic positioning, circular drilling, and position does not shift
• Special heat treatment to absorb vibration, absorb shock waves and reduce recoil
• Maintain multi-directional cutting at the same time, increase drilling speed, and ensure stable and balanced drilling force through automatic positioning
• Suitable for use with the zero-effort five-groove hammer drill
• DIAGER is the largest drill manufacturer in Europe, a professional drill manufacturer, and the only distributor of drill bits imported from France.

Instructions for use:

• Before drilling a deep hole, you must pre-drill a shorter intermediate length hole of the same specification to reduce the pressure on the drill bit.
• When drilling, it is necessary to maintain a stable pressure and remove the drill bit from the hole frequently to remove debris. Use a slow speed to drill harder materials to extend the life of the drill bit.
• Different drilling speeds are used depending on the model of the electric drill. Generally speaking, regardless of the drill bit specifications, the recommended drill speed is 300-400 revolutions per minute.
• Do not use too much force on the hammer drill when using it. Just use normal force to avoid hand fatigue.
