Product Overview
The Makita E-03377 is a high-performance 10-piece set of 50mm PH2 screwdriver bits from the elite Impact Premier range. These bits are specifically engineered to endure the extreme torque generated by modern impact drivers, featuring an advanced double torsion zone that effectively absorbs shock and vibration. This innovative design significantly reduces the risk of bit breakage, offering up to 50% longer service life than conventional impact-rated bits. Forged from a new, high-strength steel alloy, each bit is precision-machined to ensure an exact fit within Phillips screw heads, which virtually eliminates cam-out and slipping. Finished with a corrosion-resistant coating and colour-coded for rapid identification, these 50mm bits provide both the reach and durability required for intensive, repetitive fastening tasks in demanding environments.

FAQs
If you use an electric Screwdriver or an Impact Driver, you’ll need Insert Bits so you can tackle different jobs and screw types and replace Bits as they wear out. To choose the right bits, think about how long the Bits should be, the head size and even how the bits are supplied. Do you need your bits on a handy key ring, for instant bit changes while you work? Or is a hard-wearing flip-top box with a larger number of bits a better option?
Another thing to think about is whether the Bits are capable of dealing with the material you’re working with; Impact Rated or Double Torsion Bits can offer longer life and work with tougher materials than other Screwdriving Insert Bits.
