"Thank you for providing us your feedback. All band saw blades, regardless of brand, need to be ""broken in"". When new, the teeth are simply ""too sharp"". Cutting at full rate will cause fracturing of the feather edges, which will lead to premature blade failure. Breaking in a band saw blade wears off this ultra sharp edge and allows the blade to retain its cutting edge longer. Each brand has their own preferred method of blade break in, however they all share the same principles:
1) Maintain recommended band saw speed,
2) Reduce Feed pressure to 1/2 normal rate,
3) Run at these settings for the first 50 square inches of material cut (150 square inches on mild and low carbon steel).

Note: If you are unsure what the normal feed pressure is, start light. Increase feed pressure until good curly chips start to form. After cutting the recommended area, slowly increase the feed pressure until you reach your desire cutting rate. Special consideration must be given while breaking in a band saw blade on nickel-based alloys (stainless steel, inconel, hastelloy, D2 tool steel, etc.). These alloys tend to harden very quickly; therefore, sufficient feed pressure must be applied during the break in period to remove some material. As a general rule, alloys sawed at lower speeds need more pressure during break in. Your comments will be forwarded to our Product Managers for future enhancement purposes. You may return the blades back to the store within 30 days from the purchased date. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from M-F 7a-7p CST. Thank you for your time."
