Twist drill bit Yato YT-44677 190 pcs 1.3 cm diameter

The Yato YT-44677 twist drill bit set contains 190 pieces with a standard diameter of 1.3 cm designed for drilling tasks in a variety of common materials. This collection provides a broad selection of bits suitable for general workshop, construction, and maintenance use. The set is intended to deliver consistent hole sizes and withstand repeated use when used according to material and tool compatibility.

Advantages

The drill bits are manufactured to maintain cutting performance and dimensional accuracy over multiple uses, offering reliable penetration and clean hole edges. The set’s wide quantity supports continuous work without frequent tool changes, while the uniform diameter simplifies planning and measurement for repetitive drilling operations.

Suitable for

• Drilling in wood for furniture making and carpentry
• Metal drilling for light fabrication and maintenance
• Plastic and composite material drilling for assembly and repairs
• General-purpose workshop and construction tasks

Key specifications

• Total pieces in set: 190
• Nominal drill diameter: 1.3 cm
• Type: twist drill bits
• Intended applications: general-purpose drilling in various materials
• Material and finish: engineered for wear resistance and cutting stability (manufacturer-specified materials and coatings may vary)

How to use

Select an appropriate drill speed and feed rate for the material you are working with, clamp the workpiece securely, and use proper cutting fluid when drilling metal to reduce heat and extend bit life. Install the bit firmly in the drill chuck, align the bit perpendicular to the work surface where a straight hole is required, and apply steady pressure to avoid wandering. After drilling, withdraw the bit periodically to clear chips from the flutes if drilling deep holes.

Usage recommendations

For best results, match drill speed and lubrication to the material: lower speeds and cutting fluid for metals, higher speeds for wood and plastics. Inspect bits before use for damage, replace worn bits to maintain hole quality, and store the set in a dry place to prevent corrosion.
