Deep hole drill rods are mainly divided into three categories based on chip removal methods and structures
Structure: Hollow drill rod+outer V-shaped chip groove, wall thickness 3-8mm, mostly made of 42CrMo alloy steel pipe. Working mode: The coolant is injected from inside the drill rod, and the chips are discharged outward along the V-shaped groove.

Gun drill structure design (determining its processing capability)
Cutting part: single cutting edge (made of hard alloy or high-speed steel material), with an eccentric design of the cutting edge (0.1-0.5mm away from the center of the drill rod) to ensure balanced cutting force; There is a crescent shaped chip breaker at the top, which forcibly breaks the chips into short rolls to avoid blockage.

The main structure and working principle of scraping and rolling cutting tools
Scraping blade: made of hard alloy material, with multiple blades distributed, responsible for removing residual residue (usually 0.05-0.3mm) after drilling/enlarging holes. Rolling wheel: a high hardness wear-resistant alloy wheel symmetrically arranged behind the scraping blade, which undergoes plastic deformation of the hole wall metal through cold rolling to reduce roughness.

The main types and uses of deep hole cutting tools
Core function: Open up the deep hole foundation channel, determine the position and depth of the hole. Common types: gun drill, BTA drill, spray suction drill, DF drill (same as the previous classification of deep hole drill bits, it is the core starting tool for deep hole machining).

Firstly, clarify the three machining conditions for selecting suitable deep hole drill bits (selection criteria)
Ordinary steel/cast iron: High speed steel (HSS) drill bits with low cost and sufficient toughness. Difficult to process materials (stainless steel, high-temperature alloys): cobalt containing high-speed steel or solid hard alloy drill bits, heat-resistant and wear-resistant.

Compared to ordinary drill bits, deep hole drill bits have advantages
Processing capability: capable of achieving deep processing accuracy that ordinary drill bits cannot achieve. Guarantee: the guiding system ensures the straightness of the hole and the roundness error is less than 0.05mm/m
