Product details

Blade Hardness & Sharpness

- Blade material: High-carbon steel (C1045/C1050 grade) with HRC 58-60 hardness rating, ensuring exceptional edge retention and resistance to dulling.

- Precision-ground cutting edge with a 25°-30° bevel angle, enabling effortless penetration into wood, soft stone, mortar, and mild steel (≤10mm thickness).

- Edge sharpness retention: Maintains cutting efficiency for up to 50+ hours of continuous use on medium-density wood (e.g., oak, pine) without re-sharpening.

Cutting Efficiency & Power Transmission

- Impact resistance: Withstands repeated hammer strikes (up to 150N impact force) without blade deformation or chipping, thanks to heat-treated blade core and tempered edge.

- Material removal rate: Removes up to 1.2cm³ of wood per strike (tested on pine) and 0.8cm³ of mortar per strike, optimizing workflow for fast, precise shaping.

- Straightness tolerance: Blade runout ≤0.1mm over the entire length (150-250mm), ensuring clean, uniform cuts and recesses.

Durability & Corrosion Resistance

- Blade coating: Electrophoretic rust-resistant finish with salt spray test resistance of 48+ hours, preventing oxidation in humid or outdoor environments.

- Ferrule construction: Zinc-plated steel ferrule with press-fit and adhesive bonding, achieving a pull-out force of ≥200N to avoid handle-blade separation under heavy use.

- Handle durability: Hardwood (beech/maple) or glass-reinforced nylon handle with impact resistance ≥8J, resisting cracks and splinters from accidental drops (1.5m height onto concrete).

Ergonomics & Control

- Weight balance: Center of gravity located 3cm from the blade-ferrule junction, reducing wrist strain during vertical and horizontal chiseling.

- Grip performance: Non-slip rubberized or textured wood handle with a friction coefficient of ≥0.6, ensuring secure hold even with sweaty hands.

- Vibration dampening: Handle core integrated with EVA foam buffer, reducing impact vibration by 30% compared to standard solid handles, minimizing fatigue during extended operation (4+ hours).

Temperature Adaptability

- Operating temperature range: -10°C to 60°C, maintaining consistent performance in cold workshops or hot construction sites without material brittleness or softening.

Blade material: High-quality alloy steel (40Cr grade) with HRC 60-62 hardness rating, specially forged for electric hammer compatibility, ensuring excellent edge retention and resistance to dulling under high-frequency impact.

Precision-ground cutting edge with a 30°-35° bevel angle, optimized for electric hammer’s impact force transmission, enabling effortless penetration into concrete, brick, stone, and reinforced mortar without edge chipping.

Edge sharpness retention: Maintains stable cutting efficiency for up to 80+ hours of continuous use on C20-C30 concrete, resisting wear caused by high-frequency vibration and hard aggregate impact, reducing re-sharpening frequency.

Insoul HSS hole saw represent the pinnacle of performance in metalworking. Engineered by integrating 5% cobalt into premium high-speed steel (HSS), these bits are specifically designed to conquer the challenges posed by stainless steel, high-temperature alloys, and other hard-to-machine materials. The core innovation lies in their exceptional red hardness, allowing them to maintain cutting edge integrity and hardness even at temperatures exceeding 500°C, where standard HSS drill bits would fail. This makes them an indispensable tool for professional machining, fabrication, and maintenance operations demanding precision, reliability, and extended tool life.
