Conjunto de brocas Bosch HSS-G 5 unid. diâmetro 1 cm

The Bosch HSS-G 5 pcs drill bit set with 1 cm diameter contains five high-speed steel bits designed for straightforward, reliable drilling in a range of common materials. These HSS-G bits are intended for manual and machine drilling where accuracy and edge durability are required. The set provides a consistent 10 mm cutting diameter across all pieces and is packaged for easy storage and selection during work.

Advantages

HSS-G construction delivers a balance of hardness and toughness suitable for drilling in metal, wood and plastics. The straight shank design ensures stable clamping in standard chucks and quick bit changes. Precision-ground tips and flute geometry help provide fast chip removal and consistent hole quality. The uniform diameter across five bits allows for repeated use or replacement during extended tasks.

Suitable for

• Drilling holes in mild steel and non-ferrous metals
• Cutting holes in wood and plywood
• Working with plastic materials
• General workshop and DIY tasks requiring 10 mm holes

Key specifications

• Material: High-speed steel (HSS-G)
• Number of pieces: 5
• Diameter: 10 mm (1 cm)
• Shank type: Straight shank for standard chucks
• Tip: Twist/ground cutting tip for general-purpose drilling

How to use

Select an appropriate drill and clamp the straight shank securely in the chuck. Mark the drilling point and, if needed, use a center punch for improved positioning on metal. Start drilling at low speed to establish the hole, then increase speed according to material and bit performance. Apply steady, moderate pressure and allow the flutes to clear chips; for metal work use cutting lubricant to prolong bit life. Withdraw occasionally to remove chips when drilling deeper holes.

Recommendations

Use the HSS-G bits for general-purpose drilling tasks in metal, wood and plastic, avoiding excessive speeds or side loads. For prolonged use in harder materials, employ cutting fluid and moderate feed rates to maintain cutting edge life. Store bits in their case to protect the cutting edges when not in use.
