Pneumatic Double-Headed Phillips Bit CR-V Steel HRC58 1/4" Hex Shank

Product Description

The Pneumatic Double-Headed Phillips Bit is crafted from high-quality chrome-vanadium steel (CR-V), heat-treated to a Rockwell hardness of 58 for superior toughness and enhanced torque performance. The 1/4" standard hex shank fits all pneumatic screwdrivers, electric drills, and manual screwdrivers. Its double-ended phillips design allows both ends to be used—one bit delivers twice the value. Available in 65mm, 100mm, and 150mm lengths, these bits are ideal for mechanical assembly, electronics manufacturing, furniture installation, automotive repair, and industrial fastening applications.

Product Features

1. Premium CR-V Steel

The bit is forged from high-quality chrome-vanadium alloy steel and heat-treated to a hardness of HRC58, offering high strength, good toughness, excellent resistance to torsion and wear, and the ability to withstand high-intensity continuous pneumatic operation.

2. Double-Headed Phillips Design

Both ends feature a Phillips head design, allowing one screwdriver to function as two. Wearing one end allows the other to be replaced, effectively extending the screwdriver's lifespan and reducing operating costs, making it economical.

3. 1/4" Standard Hex Shank

A 1/4-inch standard hex shank, highly versatile, perfectly compatible with various pneumatic screwdrivers, electric screwdrivers, cordless drills, and manual screwdrivers. Plug and play, easy to replace parts.

4. Industrial-Grade Precision

Precision-machined tips ensure accurate dimensions and a tight fit with the screw groove, preventing slippage and damage to the screw, effectively reducing the risk of stripped screws and ensuring a high-quality tightening.

5. Multiple Length Options

Offers three commonly used lengths: 65mm, 100mm, and 150mm, meeting the needs of different depths and working conditions, allowing easy operation even in narrow spaces.

FAQ

Q1: What is the difference between double-ended and single-ended screwdriver bits?

A: Double-ended bits feature working tips on both ends, effectively serving as two bits in one; if one end wears out, you can simply flip it over to use the other, resulting in a longer lifespan and better cost-effectiveness. Single-ended bits have only one working tip but typically offer a longer shank and superior overall rigidity. Double-ended versions are generally recommended for pneumatic applications due to their economy and practicality.

Q2: Which is better: Chrome-Vanadium (Cr-V) steel or S2 steel bits?

A: S2 steel offers higher hardness (approx. HRC60) and superior wear resistance; it is a high-end industrial-grade material suitable for heavy-duty, continuous operation. Chrome Vanadium (Cr-V) steel has a hardness of around HRC58, offers good toughness, and is more cost-effective, making it suitable for most standard industrial and maintenance applications. This Cr-V bit offers excellent value for money and is a popular choice for everyday use.

Q3: Can this bit be used with an electric screwdriver?

A: Yes. The 1/4" hex shank is a universal standard, compatible with the vast majority of pneumatic screwdrivers, electric drivers, cordless drills, and manual tools featuring a 1/4" hex chuck. It can be used with any tool that accepts a 1/4" hex shank.

Q4: They come in boxes of 100; what is the minimum order quantity (MOQ)?

A: These bits are packed 100 per box and 1,200 per carton; the standard minimum order is one carton (1,200 pieces). If you require a mix of different lengths, we can arrange orders based on carton units; please contact our sales team to confirm the details.

Q5: What is the typical service life of the bit?

A: Service life depends on usage frequency, screw material, torque levels, and operating technique. In a standard industrial environment, a single double-ended Phillips bit can drive thousands to over ten thousand screws. Thanks to the double-ended design, you can switch to the other end once one is worn out, effectively extending the service life to approximately 1.5 to 2 times that of a single-ended bit.

Q6: Can you customize other specifications or tip types, such as slotted or Torx?

A: Yes. We support the customization of bits in various lengths and tip types (slotted, Torx, hex, etc.), as well as custom branding (logos) and packaging. The MOQ for custom orders is determined based on specific requirements; please contact us to discuss cooperation details.
