No, not all table saws tilt. While most modern table saws sold in the United States feature a tilting blade for creating bevel cuts, some models, especially older ones, exist without this capability or with a right-tilting blade instead of the more common left-tilting one.
Table Saw Tilt Functionality Explained
-
Purpose of Tilting: The primary purpose of a tilting table saw blade is to allow the user to make bevel cuts, where the cut edge is at an angle other than 90 degrees to the face of the material.
-
Left Tilt vs. Right Tilt: Table saws can tilt either to the left or to the right. Left-tilt saws are more prevalent in the US market today. The "tilt" refers to the direction the blade leans when creating a bevel.
-
Non-Tilting Saws: Some simpler or older table saws are designed only for making straight cuts (90-degree cuts). These saws lack the mechanism to tilt the blade.
Why the Variation?
The existence of both left and right-tilt saws boils down to design preferences and perceived safety advantages. The debate surrounding which tilt direction is "better" is ongoing in woodworking circles.
-
Safety Considerations: Arguments exist for both left and right tilt saws being safer in specific cutting scenarios. Some argue that with a left-tilt saw, the workpiece is less likely to get trapped between the blade and the fence when cutting certain bevels. However, others argue the opposite for right-tilt saws in other situations.
-
User Preference: Ultimately, the choice between a left-tilt, right-tilt, or non-tilting table saw often comes down to personal preference and the specific types of projects a woodworker typically undertakes.
Summary
While the majority of new table saws have a tilting blade, specifically a left-tilting one, it's not universally true that all table saws tilt. Some older models or budget-friendly options might lack this feature, and some saws tilt to the right.
