Re-saw Basics and Bandsaw Blades

Re-sawing is basic to wood cutting and is a useful skill in the workshop. It is useful in certain applications as well. Bandsaws are useful since they are designed to handle any standard sized board and will cut whole logs. Material hardness and texture need consideration since they are major contributors to issues like blade bounce and tooth stripping. To help assure an easy cut, there are special re-saw blades available that are extra wide to prevent bending while cutting. Their sharp teeth in a skip tooth arrangement will clear sawdust fast enough to allow for more cut time. Tooth form describes tooth shape, and for re-saw purposes, a hook …

Flex-Back and Hard-Back Bandsaw Blades

Bandsaw blades are classified by composite makeup, namely Carbon, Bi-metal, and Carbide-tipped blades. Each blade is used differently depending on the materials involved in the cutting process. Material hardness classification includes soft, hard, or tough. The ranges of carbon steel bandsaw blades are ideal by design for use in home woodworking shops. Carbon steel blades differ in the tooth design, with heat-treated teeth designed to allow for higher speed and feed rates. Increased tensile strength permits the hard-back blade to produce a straighter cut. The hardened tooth tip counters material cut resistance and increases blade lifespan. A low-cost alternative blade …

Saw Blade Selection Made Simple

Selection of the right blade for the right material in order to produce the best cut can be time-consuming. The need to undergo a lot of trial & error will lead to frustration for the bandsaw operator and unwanted down-time for the entire shop. To help make the selection process a bit easier, take a moment to consider such things as the materials to be cut, the blade dimensions, speed and feed rates, cut quality, production output, and the bandsaw machine settings. Knowing the answers to these key elements in any cutting operation will make the selection process simpler and result in obtaining the best overall …

Carbide Bandsaws and Blades

Carbide Bandsaw Blades are derived from the carbide saw, a name that originated from a circular saw blade with silver soldered carbide tips. Other names include cold cut, cold circular, cold cut-off, and circular cold saws. The carbide blade nearly replaced solid or segmented high-speed steel (HSS) blades since carbide is much harder than HSS. HSS blades use coolant to keep the surface from over-heating, but the carbide circular saw has a unique geometry of teeth that allows for heat developed during the cutting process to be transferred to and then carried away with the chips. The most common type of carbide …
