Re: hammer drills Features
There are a few features you may want to pay attention to include: A Depth Rod mounted to the drill lets you know when the bit reaches the desired depth; Variable Speed Selection allows you to adjust the drill for specific jobs. Use high speed for small holes and low speed for large holes; Reverse can retrieve a hopelessly stuck bit; Removable Side Handles give the operator better control in normal use, and can be removed in confined spaces.
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

not much can be done as the chuck is not specifically designed to handle hammer drill operations (they crack the scroll thread adjuster inside )
best get a new chuck and if you do a lot of hammering get a proper hammer drill that has a push in operation not an ordinary electrical drill with a hammer capability
The SF4000a Is a cordless Drywall Gun. Even thought it has variable speeds most people run it full speed and then press and engage the chuck to run the screws in. The variable speed is used more to back out screws in reverse
The spade bit sold with the hammer drill was actually too large for the hammer drill. We found that the spade bit had over heated (not from overuse or heavy use as only two ladies were using the hammer drill) but because the bit was too large it put too much weight on the drill. The bit had to be removed from the chuck using a hammer and force causing a bearing to come out and the chuck now needs repair. Solution repair the chuck on the hammer drill and buy a lighter spade bit. Then continue jackhammering the cement out of the shower cubicle.
Basically yes. Lower power units are usually titled as "hammer drills." Higher power units, usually labeled "rotary hammers," tend to be larger and provide bigger impact forces. But there are a few differences that are worth knowing: The rotary hammer usually have a chisel only feature, for light chiseling and masonry removal. Rotary hammers also have specially designed chucks that only accept bits specifically designed to fit their chuck. The special chuck on a rotary hammer helps hold the drill bit and prevents it from slipping during use.
Two drive systems are available on both the hammer drill and the rotary hammer models: 1. SDS (or Slotted Drive System) bits for hammer drills/rotary hammers allow the bit to slide in the chuck and enhance the hammering action of the tool. For most applications, these bits provide plenty of torque. 2. SDS Max bits are similar to SDS bits, but have larger shanks and come in larger sizes than SDS bits. These powerful bits are useful in industrial applications.
You compare the following features: Horsepower (HP) is the maximum power produced by the motor. Higher horsepower allows you to bore larger holes through tougher material. Drill presses are available with motors from 1/4 to 1 HP. Size/center drilling capacity is determined by the distance from the center of the chuck to the column. Since the press can bore a hole in a circle with a diameter two times the distance from the center of the chuck to the column, the size is listed as twice the distance from the column to the center of the chuck. A 16" drill press can drill a hole up to 8" from the edge of a straight board or at the center of a 16" diameter circle. Variable speeds allow you to drill different diameter holes through different materials without damaging the material or drill bits. Drill presses are available with five to twelve speed settings. The more speed settings, the more versatile the drill press. The table on most drill presses can be raised and lowered along the entire length of the column. It can also swivel 360° around the column for boring oddly shaped pieces. Better presses have large, tilting tables with fences. Quill travel determines the depth to which the press can bore holes. Greater quill travel allows you to bore deeper holes. Depth-stops control the depth to which the quill descends and limit the depth of the hole. Depth-stops are good for repetitive boring and dowel holes. The more precise your depth-stops, the more accurate your boring operations.
