Even With the Best Rotary Hammer - Hole Size Matters
In addition, each rotary hammer incorporates the flexibility to drill larger holes as well. Bosch SDS-plus hammers can handle carbide-tipped core bits from 2-1/2" up to 3-1/2", and SDS-max hammers can handle carbide-tipped core bits from three inches up to 6" and thru-hole bits up to 3-1/8". The exact size core and thru-hole bits are dependent on the hammer size.
Though occasional rotary drilling at full capacity is possible, you're always better off opting for the next larger hammer for continuous larger hole drilling. Like any other tool, constantly pushing a hammer to its extremes will eventually lead to failure. Investing in the next larger hammer upfront will pay off in the long run.
By selecting the best rotary hammer designed to drill the holes that are needed, users can guarantee faster and more efficient performance. One critical point to keep in mind when using a hammer for rotary drilling is to let the tool do the work; applying too much pressure on these tools can actually decrease performance.
The Best Rotary Hammer Requires The Best Bits.
When it comes to rotary hammer carbide bits for rotary drilling, it’s best to think of hammers as a system. With all the improvements in power tools over the past few years, the carbide bit technology has helped deliver even more efficiency.
Optimized flute designs help remove dust quicker, extending the speed as well as the life of the drill. Newer Full Head Carbide Bits provides added durability with up to four times the life of standard bits. Some specialty bits include dedicated rebar cutters to “stop bits" that control depth to avoid post tension cables.
Bosch also recently added further dust control with the Speed Clean bits that remove dust directly from the hole while drilling, saving time and helping meet the new OSHA dust control requirements.
Rotary hammer bits have been upgraded over the years to keep pace with the increased hammer impact energy. Bosch rotary hammers and accessories, such as bits and spades, have been maximized with the industry standard SDS system provides the full benefit of optimal energy transfer to the work surface. Matching up the right tool and accessory system leads to faster and more efficient drilling and ensures you get the value out of your tools instead of overheating them, leading to costly down time and repairs. Making the right decision on the best rotary hammer and associated concrete and masonry bits makes your work easier, gets your work done faster and ultimately, your tools will last longer.
