Blue Spot Tools 25 Piece 1/2" Interchangeable Impact Bit Set (H6-H19) (T30-T70) (M6-M18)

MPN: 01494

Barcode: 5028734014945

Size: 1/2"

Weight: 2.26kg

Overview:

This 25-piece set from Blue Spot Tools covers hex, Torx, and spline bit profiles. Each bit is manufactured from S2 steel, then heat-treated, hardened, and tempered. The blackened phosphate finish protects against corrosion during storage and use.

A 1/2" chrome molybdenum drive adaptor connects the bits to ratchets, breaker bars, and air tools. The set covers the most widely used sizes across all three bit profiles. This suits automotive repair, drivetrain work, and general mechanical maintenance.

All items store neatly in the included carrying case, keeping the set together between jobs. This set comes backed by the Blue Spot Tools lifetime guarantee.

What's Included

• Hex Bits (x8): H6, H7, H8, H10, H12, H14, H17, H19
• Torx Bits (x8): T30, T40, T45, T47, T50, T55, T60, T70
• Spline Bits (x8): M6, M8, M9, M10, M12, M14, M16, M18
• Drive Adaptor: 1x 1/2" Drive Adaptor Socket
• Hex Key: 1x 5mm

Key Features and Benefits

• S2 Steel Construction: Tolerates shock and vibration - bits hold their form even under repeated heavy impacts.
• Heat Treatment: Prevents bit tips from rounding or deforming through sustained high-torque use.
• Phosphate Coating: Keeps surface oxidation at bay when bits sit in storage between jobs.
• Chrome Molybdenum Adaptor: Resists deformation under high torque loads.
• Three Bit Profiles: Hex, Torx, and spline covered in one set - fewer separate sets to buy and carry.
• Carrying Case: Holds all pieces together - nothing gets misplaced between jobs.

How to Use

• Select the Bit: Choose the correct profile (hex, Torx, or spline) and size to match the fastener head.

• Insert Into the Adaptor: Push the chosen bit into the 1/2" drive adaptor until it seats firmly.

• Attach the Drive Tool: Connect the adaptor to a ratchet, breaker bar, or air impact wrench.

• Seat the Bit: Press the bit firmly into the fastener head before applying torque.

• Apply Torque: Drive in the correct direction to tighten or loosen the fastener.

Frequently Asked Questions (FAQs)

• What is S2 steel, and why is it used for impact bits?
  S2 is a shock-resisting tool steel alloy engineered to handle high-impact forces and vibration. It reaches a hardness of around HRC 58-62 when heat-treated. This makes it well-suited to impact bits that must handle sudden high-torque loads without fracturing.

• What are spline bits used for?
  Spline bits - also known as XZN or triple-square bits - are designed for fasteners with a 12-point star-shaped recess. They are common on European vehicles, particularly Volkswagen Audi Group models. You will find them on brake calliper carriers, drivetrain components, and cylinder head bolts.

• Are Torx bits the same as star bits?
  Yes. Torx and star bits refer to the same six-pointed star-shaped drive format. Torx is a trade name, while "star bit" is the widely used generic term for the same profile.

• What is chrome molybdenum used for in drive tools?
  Chrome molybdenum (CrMo) is an alloy steel used in sockets and drive adaptors. It offers high tensile strength and resists deformation under torque. This makes it a standard material for 1/2" drive components used with ratchets and air impact tools.

• What does a blackened phosphate finish do to tool bits?
  Blackened phosphate is a chemical surface treatment that bonds a phosphate layer to the steel surface. This coating slows the rate of oxidation when bits are stored or used in damp conditions, providing protection against surface rust.

Summary

This 25-piece set packs S2 steel hex, Torx, and spline bits alongside a chrome molybdenum 1/2" drive adaptor. Each bit is heat-treated and tempered for use with ratchets, breaker bars, and air tools. A carrying case and the Blue Spot Tools lifetime guarantee are included.
