Bosch PointTeQ 18-Piece Set
The Bosch Professional 18-piece PointTeQ drill bit set focuses on metal drilling with a TipTeQ design to speed starts and reduce wandering. Its self-centering tip helps you begin holes without checking alignment repeatedly, making metalwork more efficient in the workshop or on-site. The set is designed to deliver a higher drilling rate, which in turn generates less heat and wear during extended metal drilling tasks. The cylindrical shank is compatible with standard three-jaw chucks, enabling broad compatibility with popular drills in the UK market.
Bosch PointTeQ 25-Piece Set
This larger Bosch ProBox Metal Drill Bit Set expands on the PointTeQ concept with 25 pieces for metal work. The PointTeQ tip design emphasizes fast drilling with improved heat management to minimise wear. The set’s extended range supports various hole sizes, and the cylindrical shanks provide compatibility with common drill chucks for quick tool changes on site or in a busy workshop environment.
Bosch PointTeQ 19-Piece Set
Designed to save time in metal drilling, this 19-piece Bosch set uses the PointTeQ tip for quick starts and reduced wandering. The bits’ design helps maintain sharpness with less heat buildup, extending bit life during high-speed drilling operations. The self-centering tip supports accurate hole starts, which is particularly beneficial when working with stainless steel or other tough metals.
Makita D-72849 TiN Set
The Makita D-72849 10-piece set features HSS bits with a TiN coating for improved hardness and wear resistance, making them suitable for metal drilling and longer life. An economy-minded collection, these straight-shank bits fit standard chucks and provide reliable performance for DIY projects and light professional work. The TiN coating reduces friction, allowing smoother cutting and less heat generation during operation.
Bosch PointTeQ 10-Piece Set
This 10-piece Bosch set concentrates on rapid metal drilling with reduced shank for easier handling in tight spaces. The PointTeQ design emphasizes efficient starts and durability, helping professionals complete tasks with fewer interruptions caused by bit wear or misalignment. The bits are well-suited to everyday metalworking tasks, including holes in steel and other alloys, making them a practical addition to a contractor’s toolkit.
3Pcs Premium HSS & Cobalt Set
This premium 3-piece set uses M35 cobalt steel for enhanced hardness and durability, with TiAlN coating improving wear resistance. The design includes multiple sizes within each bit, enabling step drilling through diverse materials, including stainless steel and other metals. The straight shank supports stable centering and accurate drilling, while the TiAlN coating helps maintain sharpness across extended use.
Gasea Titanium Coated Drill Bits
The Gasea 6-piece drill bit set features HSS with titanium coating, offering sharper edges and faster cutting with less effort. The 1/4-inch hex shank provides compatibility with quick-change adapters, making them convenient for drilling, routing, filing, and cutting across wood, plastic, and light metal tasks. The hardness specification up to 60-63 HRC supports sustained performance in practical projects.
JTWEB 13Pack HSS Twist Drill Bits
The JTWEB 13-pack focuses on extreme heat resistance and precision. Made from M35 cobalt steel with a high Rockwell hardness up to 67, these bits are designed for faster cutting and longer life, particularly when drilling tough metals. The straight shank aids stable centering, and the 135-degree Quick-Cut points are self-centering to reduce wandering, especially useful for metal and composite materials. A versatile choice for metalworkers and DIY enthusiasts alike.
Buying Guide
- Material and coating: TiN or TiAlN coatings reduce friction and wear, extending bit life. Cobalt alloys (M35) offer higher heat resistance for stainless steel and other hard metals.
- Tip design: PointTeQ tips provide self-centering starts and quicker penetration, reducing walk or wander during initial drilling.
- Shank compatibility: Straight shanks fit common drill chucks; reduced shank designs help in tight spaces, but ensure chuck clearance is adequate for larger bits.
- Set size and range: Larger sets cover a wider hole-size range, beneficial for professional metalworking. For occasional DIY, a focused set with common sizes may be more economical.
- Heat management: High-speed drilling generates heat; selecting bits with coatings and efficient geometry minimizes heat buildup, preserving bit sharpness.
- Durability vs price: Premium cobalt or TiN/TiAlN-coated bits last longer under heavy use but may cost more upfront. Consider expected workloads and material hardness when choosing.
- Brand support and compatibility: Trusted brands offer consistent quality and easier replacement parts or extended warranties through UK retailers.
- Intended material: For metal-heavy projects, prioritize bits designed for metal with self-centering tips. For mixed media, consider versatile sets with a mix of metal and wood-friendly bits.
