Product Description
Milwaukee Jig Saw High Speed Steel 14 TPI 2-3/4 in. — 5 Pack
Model Number: 48-42-0101
The Milwaukee 48-42-0101 is a 5-pack of 2-3/4 in. High Speed Steel 14 TPI Jig Saw Blades — precision-ground HSS blades engineered for clean, accurate cutting through thin metal, sheet metal, aluminum, copper, stainless steel sheet, and other metal materials where the fine 14 TPI tooth geometry produces the smooth, accurate cut surfaces that precision metalworking and metal fabrication applications require. High-speed steel jig saw blades offer the hardness profile needed for metal cutting across a range of metal materials including ferrous and non-ferrous metals, providing a cost-effective option for metal cutting in lower-volume applications where bi-metal blades' extended life advantage does not justify the cost premium. Milwaukee designs and manufactures its jig saw blades specifically for professional users, with material specification, tooth geometry, tooth set, and heat treatment all optimized for the professional-use cutting performance and cut quality requirements that distinguish Milwaukee's blade specifications from economy-grade alternatives.
The 14 TPI tooth count is the standard fine-tooth specification for metal jig saw cutting — higher TPI means more teeth in simultaneous contact with thin metal workpieces, which reduces per-tooth material removal and cutting vibration for smooth, accurate cuts with minimal burr formation on the cut edge. The 2-3/4 in. blade length is the appropriate specification for thin metal and sheet material cutting applications where short blade length provides adequate material clearance while maintaining a stiff, controlled blade that deflects less under lateral cutting forces than longer blades in the same material. Short blade length also provides better access in the tight clearance cutting situations common in metal fabrication and HVAC sheet metal work where jig saws must cut in confined spaces near other structure and components. The 5-pack provides an economical supply of replacement blades for projects requiring multiple blade changes from progressive blade wear in metal cutting applications.
For higher-volume or more demanding metal cutting applications where longer blade life justifies the cost premium, Milwaukee's bi-metal jig saw blade versions in comparable TPI specifications provide significantly extended service life through the HSS/alloy steel bi-metal construction.
