They are longer and heavier than hand hacksaw blades, designed for the higher loads and continuous duty of machine cutting.\u003c\/p\u003e\n\u003ch3\u003eQ: How do I choose the right TPI (teeth per inch) for a power hacksaw?\u003c\/h3\u003e\n\u003cp\u003eSelect TPI by the wall thickness of material being cut. 14 TPI suits thin-wall tube and sheet up to approximately 3 mm wall thickness. 10 TPI is the workshop standard for most structural sections with walls of 3–12 mm. 6 TPI suits thick solid bar and heavy structural sections. The 3-tooth rule applies: always keep at least 3 teeth in contact with the workpiece — too few teeth causes tooth stripping and premature blade failure.\u003c\/p\u003e\n\u003ch3\u003eQ: What is the difference between an HSS all-hard and an HSS bi-metal power hacksaw blade?\u003c\/h3\u003e\n\u003cp\u003eAn HSS all-hard blade is made from a single high-speed steel alloy throughout — harder and more wear-resistant but more brittle and prone to tooth breakage on mixed materials or vibration. A bi-metal blade has HSS teeth welded to a flexible spring steel body, giving the cutting edge hardness of HSS with the flexibility of spring steel — better suited to structural sections, mixed materials, and applications where blade flexing could snap an all-hard blade.\u003c\/p\u003e\n\u003ch3\u003eQ: When should an HSS cobalt power hacksaw blade be specified?\u003c\/h3\u003e\n\u003cp\u003eHSS cobalt (M42) blades are specified for stainless steel, tough alloys, and high-production cutting where extended blade life is the priority. The cobalt content increases hot hardness and wear resistance, maintaining cutting efficiency over longer production runs than standard M2 HSS blades.\u003c\/p\u003e\n\u003ch3\u003eQ: Is cutting fluid required on a power hacksaw?\u003c\/h3\u003e\n\u003cp\u003eYes. Cutting fluid is mandatory on power hacksaws — it cools the blade and the cut, lubricates the teeth, and extends blade life significantly compared to dry cutting. Always apply the appropriate cutting fluid for the material being cut; dry cutting on metal generates excessive heat that rapidly dulls or damages the blade teeth.\u003c\/p\u003e","products":[{"product_id":"sutton-h201-300mm-power-saw-blade-all-hard-high-speed-steel","title":"Sutton H201 300mm Power Saw Blade - All Hard High Speed Steel","description":"\u003cdiv style=\"max-width:680px;width:100%;padding:12px 0;font-family:Arial,sans-serif;\"\u003e\n\u003cdiv style=\"display:flex;align-items:flex-start;justify-content:space-between;border-top:1px solid #e0e0e0;border-bottom:1px solid #e0e0e0;padding:16px 0;margin-bottom:24px;\"\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e◆\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eIndustrial quality\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e●\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eWorkshop and trade duty\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e▲\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eSutton Tools quality\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:14px;line-height:1.6;color:#444;margin:0;\"\u003eSutton Tools industrial quality tool, made for workshop and trade use.
