Complete Buying Guide for Hammer Drill 7kg
Essential Factors We Consider
When you are looking for a hammer drill 7kg, the most important factor is Impact Energy, measured in Joules. A drill might have a high amperage, but if the Joules are low, you’ll spend more time vibrating and less time drilling. We also look for vibration control. Hammering into concrete is punishing on the joints, so look for “SHOCKS” or anti-vibration handles to keep your hands from going numb.
Budget Planning
You don’t always need to spend $300 to get a good drill. If you are a professional, the Bosch Bulldog is worth every penny for its longevity. However, for a one-off home renovation, brands like WORKPRO or Berserker offer incredible “bang for your buck” and will easily survive a few years of light-to-medium use.
Final Thoughts
Choosing the right hammer drill depends on your frequency of use and the hardness of the material you’re tackling. Whether you choose the cordless convenience of a DEWALT or the industrial strength of a corded Seesii, having the right tool makes the difference between a project that’s a joy and one that’s a nightmare.
Frequently Asked Questions
Q: Can I use regular drill bits in an SDS hammer drill?
A: No, SDS (Slotted Drive System) chucks require specific SDS bits that have grooves on the shank to allow the bit to slide back and forth for hammering. Some drills come with an adapter, but for the best results, use the correct bit type.
Q: What is the benefit of a brushless motor?
A: Brushless motors are more efficient, run cooler, and last longer than brushed motors. In cordless drills, they also provide significantly better battery life and more consistent power under load.
Q: How often should I grease my rotary hammer?
A: Most modern rotary hammers have a grease port or come pre-lubricated for life. However, it is a good practice to put a small dab of grease on the shank of your SDS bit before inserting it to keep the chuck moving smoothly.
Q: Is a hammer drill the same as a demolition hammer?
A: Not exactly. A hammer drill can both rotate and hammer, making it ideal for making holes. A demolition hammer only hammers and is used for breaking up material. Many rotary hammers have a “hammer only” mode, making them a hybrid tool.
