KillerTech Broadhead 100 Grain 3-Pack - Speed-Lok Expandable

In this review the KillerTech Broadhead 100 Grain 3-Pack is evaluated for hunters who rely on modern high-speed crossbows and vertical bows. The bottom line: these broadheads are built for durability and reliable in-flight performance thanks to the unique Speed-Lok system that removes fragile O-rings and springs, making them a strong choice for serious big-game hunters who need blades that stay closed until impact.

Key Features

• Speed-Lok system: Eliminates O-rings, springs and clips so blades remain closed in flight and avoid premature deployment at high velocities.
• 420 stainless steel blades: Blades are 50% thicker than many competitors, providing greater resistance to bending or chipping on bone hits.
• 1.5 in cutting diameter: The two-blade design creates a large wound channel for faster, more ethical takedowns on big game.
• Aircraft aluminum ferrule: A lightweight but strong ferrule paired with a stainless tip improves impact durability without unbalancing the arrow.
• Balanced and spin-tested: Engineered to match field point flight so hunters retain familiar accuracy and grouping.
• High-speed performance: Designed to function reliably over 500 FPS where other expandables can fail.

Who It's For

The KillerTech Broadhead 100 Grain 3-Pack is best for crossbow and vertical bow hunters who shoot high velocity setups and need a dependable expandable that does not open in flight. It suits hunters targeting medium to large big game who prioritize heavy cutting power and robust construction.

Hunters who mostly use low-velocity setups or prefer mechanical broadheads with different blade counts or replaceable blades might look elsewhere; likewise, target-only shooters who want practice heads should choose dedicated field points instead of these hunting-grade broadheads.

Pros & Cons

Pros

• Very reliable blade retention in flight thanks to the Speed-Lok mechanism.
• Thicker 420 stainless blades resist damage on bone impacts for better durability.
• Large 1.5 in cut creates significant wound channels for quick takedowns.
• Balanced and spin-tested to mirror field point flight for consistent accuracy.

Cons

• Two-blade expandables provide less fragmentation than multi-blade options for some hunters' preferences.
• Heavier, thicker blades may require confirmation of broadhead-tuning on some setups.
