The Bosch 4100-09 Table Saw is supposed to be a durable and high performing table saw. According to Bosch, the manufacturer of the 4100-09 table saw, the tool boasts essential new features and improvements, which makes it a top tool in its category. Time to have a closer look at these claims I thought. The overall rating of 4.4 out of 5 is quite the guarantor that this tool definitely delivers what it says it will. Sifting through the many vibrant reviews that the users had left on Amazon, I found one from A. Babcock from California. Quite an insightful review. He has been using the 4100-09 for the past few months, and seemed quite happy with its performance.
He bought the 4100-09 primarily wooed by its safety features. Let’s break up these features and see why they make the tool ‘safe’.
Safety feature 1: Riving-Knife
One of the safety features in the 4100-09 is the riving-knife. Now what is it and how does it add to the safety of the tool? For those who use a table saw for ripping wood, one of the major causes for injuries is kickback. The riving-knife is basically one of the ways by which a kickback can be prevented. The riving knife is a curved, thin, fin-shaped strip which is placed behind the blade and sits above the table. The riving knife basically prevents a wood piece from closing back, or pinching, as it is pushed for cutting. It also protects the wood from drifting away from the rip fence and catching the back of the blade. The riving-knife and the splitter are most often and mistakenly thought to be synonymous. This could be due to the fact that most functions in the two are similar. However, the splitter is fitted separately to the saw and is not attached to a blade rising device. This means its height remains constant all the time, irrespective of the blade height. When the blade is lowered and the space between the blade and the splitter increases this may cause a kickback. On the other hand, the riving knife is secured to the blade rising device and adjusts its height based on the height of the blade thus providing more safety from kickback.
Safety feature 2: The blade guard
The blade guard ensures that there is no accidental hand or body contact with the blades. What makes the blade guard of 4100-09 unique? Most table saws today come with the blade guard feature, but many find it to be more of a hassle as it blocks the view of the blade. Many thus prefer not to use it, creating a hazardous situation. Addressing this concern, the blade guard of the 4100-09 is designed only to keep your hands and body off the blade, not your eyes. This means that you have a clear unobstructed view of the cutting area. That means that you can work with the blade guard on, effectively ripping your wood without the fear of ripping yourself apart!
Safety feature 3: The anti-kickback pawls
The pawls are small pieces of metal which are spring loaded and can be attached to both sides of the riving-knife. It has teeth that jut downward toward the table top. When a wood is passed through the blade, the pawls rise and let the wood glide along. However, in case of a kickback, the downward protruding tooth grabs the wood and ensures that it is secured in its place. One disadvantage of the pawls though, is that they can damage the top surface of the work piece.
These safety features, when combined with the other features of the Bosch 4100-09 like the digital measuring system which ensures that your measurements are accurate, a square lock rip fence which means you have an accurate alignment with the blade to cut with precision, a complete on-tool storage, an arbor lock for quick and easy blade change, a wrap around sub base with handle and a gravity rise stand that makes it a portable and easy to store tool. The 4100-09 comes with a 15 amp motor and a maximum of 3,600 RPM and a 21 inch rip capacity. To summarise, it is a mini beast made to handle large tasks with ease. I cast my vote for the Bosch 4100-09 Table Saw.
